Where pi is 3.14 find the area of a circle with a radius of 20cm?
Oh, what a happy little question! To find the area of a circle, we use the formula A = πr^2, where A is the area, π is approximately 3.14, and r is the radius. So, for a circle with a radius of 20 cm, the area would be A = 3.14 x 20 x 20 = 1256 square centimeters. Just imagine all the beautiful colors you could paint in that space!
Well, honey, 20 times x is just 20x. It's as simple as that. Multiply that x by 20 and you've got your answer. Math doesn't have to be so complicated, darling.
What is the square root 15 Times Square root 5?
The square root of 15 times the square root of 5 can be simplified as the square root of (15 * 5), which equals the square root of 75. The square root of 75 can be further simplified as 5 times the square root of 3. Therefore, the square root of 15 times the square root of 5 is equivalent to 5 times the square root of 3.
Volume of a cube with length 4 inches?
There can be many volumes with only a length of 4 inches for a cube.
the formula to find volume is volume=length x width x height.
an example to find the volume of a cube with length 4 inches is,
v=lxwxh
v=4x2x3
v=8x3
v=24 inches cubed
Well, darling, if you want to know how much compound interest you'll get on Rs 9650 at a 6% rate over 3 years, I'll tell you straight. The formula for compound interest is A = P(1 + r/n)^(nt), where A is the amount, P is the principal, r is the rate, n is the number of times interest is compounded per year, and t is the time in years. Plug in those numbers and you'll find out the compound interest you're looking for. Just remember, math doesn't care about your feelings, honey.
To find the area of a shape, we need to know the shape of the object. If the object is a square, we can use the formula A = s^2, where A is the area and s is the length of one side. If the object is a circle, we can use the formula A = πr^2, where A is the area and r is the radius. Without knowing the shape of the object, we cannot calculate the area of 42.5 cm.
If the length of a square is doubled how is the area affected?
The Area of a square can be written as it's side length^2, or
A = s^2
if the side length is doubled, then s' is 2s.
A' = (s')^2
A' = (2s)^2
A' = 4s^2 = 4*A
When the side length is doubled, the area increases by a factor of 4
How many Hershey kisses can fit in a gallon jar?
To determine the number of Hershey kisses that can fit in a gallon jar, we first need to establish the volume of a single Hershey kiss. Typically, a Hershey kiss has a volume of about 0.25 cubic inches. A gallon is equivalent to 231 cubic inches. Dividing the volume of the gallon jar by the volume of a single Hershey kiss gives us approximately 924 Hershey kisses that can fit in a gallon jar.
What is the absolute value of l-6l?
The absolute value of |l-6| is the distance between the number 'l' and the number 6 on the number line, regardless of the direction. If l is greater than 6, the absolute value of |l-6| is l-6. If l is less than 6, the absolute value of |l-6| is 6-l. In either case, the absolute value function ensures that the result is always non-negative.
What is the exponential notation for 32768?
The exponential notation for 32768 is 3.2768 x 10^4. This is because 32768 can be expressed as 3.2768 multiplied by 10 raised to the power of 4. In exponential notation, the base (3.2768) is multiplied by 10 raised to the exponent (4), indicating the number of decimal places the decimal point must move to the right to return to the original number.
To convert feet to yards you must?
There are 3 feet in 1 yard. To convert 'feet' to 'yards' divide by '3'.
Here is the full Linear Imperial Table of Length.
12 inches = 1 foot
3 feet = 1 yard
22 yards = 1 chain
10 chains = 1 furlong
8 furlongs = 1 mile.
36 cm is the perimeter of the rectangle.
Since it is the perimeter, there will be two long sides and two short sides. , making the four sides.
This can be algebraically expressed as
P = 2(l + s)
P = 2l + 2s
Substituting
P = 36 sm
s = 4 cm ( assumed).
36 cm = 2l + 2(4cm)
36 cm = 2l + 8 cm
2l = 36 cm - 8cm ( Note the change of sign , when 'crossing the '=' sign
2l = 28 cm
Divide both sides by '2'
l = 14 cm ( is the length).
Which digit has the least value in 456802?
Well, honey, in the number 456802, the digit with the least value is 0. It's like the extra in a movie - it's there to fill space but doesn't really bring much to the table. So, yeah, that 0 is just hanging out, being all insignificant and whatnot.
What is the length and width of 1.5 acres?
To determine the length and width of 1.5 acres, we need to know the shape of the area. Since acres are a unit of area and not length or width, we would need to define the shape of the area to calculate the dimensions. If we assume a rectangular shape, we can use the formula for the area of a rectangle (length x width = area) to find the dimensions. For 1.5 acres, we would need more information about the shape to provide specific dimensions.
Does every non vertical line have a slope and a intercept?
Yes, every non-vertical line can be represented by the equation y = mx + b, where m is the slope of the line and b is the y-intercept. The slope of a line represents the rate of change of the line, while the y-intercept is the point where the line intersects the y-axis. Therefore, every non-vertical line has both a slope and a y-intercept.
What is the proper thread notation for a 40 mm screw with 14mm thread 1.5 mm pitch?
The proper thread notation for a 40 mm screw with a 14 mm thread and a 1.5 mm pitch would be M14x1.5. In this notation, "M" indicates a metric thread, "14" represents the nominal diameter of the screw in millimeters, and "1.5" signifies the pitch of the thread in millimeters. This notation is commonly used in engineering and manufacturing to specify the thread details of screws and bolts.
Which is greater 3200 mm or 340 cm?
340 cm would be greater than 3200 mm as 340 cm is equivalent to 3400 mm (340 x 10). So, from there, do the math. 3400 > 3200.
Oh, isn't that a happy little question! There are many ways to make 11 with math. You could add 5 and 6 together, or 7 and 4, or even 10 and 1. Just like painting, there are many different ways to create something beautiful in math!
What is the area and perimeter 34 ft width by 10ft length?
To calculate the area multiply the length by width. In this case 34*10=340ft
To calculate the perimeter, you must find the total of all the sides by adding them all together. This would depend on the shape/the number of sides.
Assuming this is a rectangle, the perimeter would be 34+34+10+10=88ft.
How many 4 digit numbers that are multiples of 9?
Well, honey, to find the number of 4-digit multiples of 9, you just need to divide the largest 4-digit multiple of 9 (9999) by 9 and subtract the smallest 4-digit multiple of 9 (1008) divided by 9. So, 9999 ÷ 9 - 1008 ÷ 9 = 1111 - 112 = 999. That's right, there are 999 4-digit numbers that are multiples of 9.
What are the first nine digits of pi?
Oh, dude, the first nine digits of pi are 3.14159265. It's like the opening act of the never-ending show that is pi. Just a bunch of numbers hanging out, doing their thing, never knowing when to stop. Enjoy the ride, my friend.
What is a fraction equivalent to 10 over 100?
Oh, dude, that's an easy one. So, 10 over 100 is the same as 1 over 10. It's like reducing fractions, you know? Just divide the numerator and denominator by the greatest common factor, and boom, you've got your equivalent fraction. Easy peasy lemon squeezy!
What is a forty sided shape called?
A forty-sided shape is called a tetracontagon. The prefix "tetra-" signifies the number four, and "-contagon" denotes a polygon with a specified number of sides. In geometry, polygons are classified based on the number of sides they have, with a tetracontagon being a specific type of polygon with forty sides.
