How much would 1 psi be if it was spreaded over an area of 0.5 Sq Ft?
0.5 Sq Ft is one half of a square foot. A square foot is an area 1 foot long by one foot wide. A square foot can also be described in inches instead, so the area of one square foot is 12 inches long by 12 inches wide, or 144 square inches. 0.5 Sq Ft is half a square foot, and is equal to 144 square inches multiplied by 0.5, or one half. So half a square foot equals 72 square inches. 1 psi is one pound per square inch. If you spread 1 psi over an area of 72 square inches, you divide the pressure quantity by the area quantity: 1 psi divided by 72 square inches = 1/72 psi, or 0.0139psi.
A constant that multiplies a variable?
A constant that multiplies a variable is no longer a constant. By its very definition, a constant is something that can never be different. The result of variable multiplication is thus a variable, not a constant.I would say that the above answer is not necessarily true. The common equation for the area of a circle is: area = pi * r2The fact that you are multiplying the mathematical constant pi by a variable does not change the value of pi.Agree with the second answer. Jsut to add, a constant that multplies a variable is called a coefficient.
How large is 300px?
The physical size of a pixel is going to depend on the resolution of the device displaying it. Resolution is typically measured in Dots per Inch (DPI). The general formula to convert from pixels to inches is: Pixels / DPI = Size in Inches. For example, at 75 DPI (typical CRT display) 300px would be 4 inches; while at 150DPI (typical cell phone display) 300px would be 2 inches.
What is vacuum measured in?
vacuum is measured in pressure. To get a vacuum you need a negative pressure. that would be inches of mercury hg
Why would you use a formula to determine the circumference of a circle rather than measuring the circumference?
Because the circumference of a circle isn't a straight line its hard to measure, even if you have a flexi-ruler, your never going to be able to line it up to get an exact measurement. Therefore its much easier to measure the diameter and use the formula
What is the circumference of 324 square inches?
Assuming it is a circle, it is about 63.8 inches, a square would be 72 inches.
How many square inches in a 4 inch diameter?
In a circle with a diameter of 4, there would be approximately 12.56 square inches in the circle.
What would be the area of a circle with a radius of 4 inches?
The area would be 50.3 square inches.
How many square inches are in a 2 inch circle?
The phrase "two inch circle" implies that the circle's area has already been calculated as "two square inches". However, if you truly meant that the circle had a diameter of two inches, it's area would be pi. Alternatively, if you meant a radius of two inches, the area would be 4pi.
How many square inches in a five inch circle?
That would depend on what you mean by "five inch circle".
What is the area of a circle with a diameter of 16in.?
The area of a circle can be found using the formula A = πr^2. Given that the diameter is 16 inches, the radius would be half of that, which is 8 inches. Therefore, the area of the circle is A = π(8 inches)^2, which simplifies to an area of 64π square inches or approximately 201.06 square inches.
What is the area of a quarter circle with radius 6 inches?
That would be 1/4 of the area of the entire circle. pi * r^2/4 (or πr2/4). Area of a circle = pi*62 = 113.0973355 or about 113 square inches, which, when divided by 4, gives you 28.25 square inches.
Mark has a piece of string 12 inches long he shapes string into rectangle that encloses an area of 5 square inches Can Mark enclose a greater area with the same string If sowhat is the area?
If Mark makes a circle, that circle would have a circumference of 12 inches. The formula for circumference is pi times diameter, so the circumference divided by pi will give you the diameter of 3.82 inches. Divide this by 2 to get the radius of 1.91 inches. Area of a circle is pi times the radius squared. 1.91 squared is 3.6481. Multiply this by pi to get 11.46 square inches of area inside the circle. A circle is always the most efficient use of space possible given a fixed perimeter. If Mark makes a square with equal sides where all sides are 3 inches, the area would be 9 square inches. 3 X 3 = 9
What is the area of a square with a radius of 6?
A radius is used to measure a circle; squares do not have a radius, they would be measured by a side. If a square has a side that measures 6 inches, then it's area is 36 square inches. Note that without a unit of measurement (inches, or whatever it is) you do not have a meaningful answer.
How many square inches in half inch dia?
Assuming a circle with a diameter of one half inch, A = 2Ï€r so the area in square inches would be half of pi or about 1.57 in2.
What is the area of a circle whose radius 108 inches?
Area of a circle is calculated by taking the radius squared times pi (3.14 approx.). 108 x 108 = 11,664 11,664 x 3.14 = 36,624.96 The area of a circle with a radius of 108 inches would be 36,624.96 square inches.
If the circle is 8 inches what would be the circumference?
If the circle is 8 inches in diameter, its circumference would be: 25.13 inches (diameter x Pi = circumference)
