What is the formula to find area of circle?
The formula to find area is you do the radius squared times pi or 3.14
How do you find the measurement of an arc or angle on a circle?
the general formula is arc length is equal the radius times the angle. s=r< s=arc length r=radius <=angle
What is the formula to find a area of a circle?
pi times the square of the radius A=pi*(r^2)
How do you find circumference?
The formula is 2 times radius times pi or the diameter times pi. Circumference is 2r times pi. Assuming you are referring to a circle.
How do you solve surface area of a cone?
The first step in finding the surface area of a cone is to measure the radius of the circle part of the cone. The next step is to find the area of the circle, or base. The area of a circle is 3.14 times the radius squared (πr2). Now, you will need to find the area of the cone itself. In order to do this, you must measure the side (slant height) of the cone. Make sure you use the same form of measurement as the radius.You can now use the measurement of the side to find the area of the cone. The formula for the area of a cone is 3.14 times the radius times the side (πrl).So the surface area of the cone equals the area of the circle plus the area of the cone and the final formula is given by:SA = πr2 + πrl
What is the circumfrance of a circle and how do you find it?
the circumference of a circle is the length around the outer edge. and you find it by using the formula 2 times pi times the radius of the circle
What is the formula to find area of circle?
The formula to find area is you do the radius squared times pi or 3.14
How do you find the measurement of an arc or angle on a circle?
the general formula is arc length is equal the radius times the angle. s=r< s=arc length r=radius <=angle
What is the formula to find the shaded area of a circle?
The answer will depend on what part of the circle is shaded.Yes, that's sorta true. I think you are asking on how to find the area of a sector in a circle. If so, here's the formula: A= N/360 (πr^2)or akaArea of shaded area equal to the measurement of the central angle divided by 360 times pi to the second power.:)Just an EXAMPLE. A = 196/360 (π16^2)
What is the formula to find a area of a circle?
pi times the square of the radius A=pi*(r^2)
How do you find the circumfirence of a circle?
The circumference of a circle is the distance all around the edge of the circle. To find the circumference of a circle, you use the formula C equals 2 times pi times r, where pi is equal to 22 over 7 and r is the radius.
What is pie r2?
Pie r2 is the formula needed to find out the area of a circle you have to square the radius of the circle (half the diameter of the circle) two times (btw square means times the number by it self) and times the answer by pie which is 3.14
How do you find out the circumfrance of a circle?
To find the circumfrance of a circle, you need to multiply 2 times pi, times the circle's radius. If you don't know what that is, you multiply two times pi, and pi equals 3.14, and then multiply that by the radius, which is the measurement of half the circl'e diameter. the diameter is the distance from one side of the circle, to the exact opposite. you measure this with a ruler. HALF the measurement of the diameter is the radius. Example---the diameter of a circle is 20 cm. half the diameter is 10 cm, which is the radius. Multiply 2 times pi[which equals 3.14], times the radius. Good luck!
What is the formula doe for the area of a circle?
The formula to find the area of a circle is: A = pi * r2
How do you find circumference?
The formula is 2 times radius times pi or the diameter times pi. Circumference is 2r times pi. Assuming you are referring to a circle.
What is the formula to find area?
the formula for the area of a square or rectangle is length times height the formula for the area of a circle is pi times radius squared the formula for the area of a triangle is half base times height the formula for the area of a trapezoid is 1/2(top + bottom) times height
Formula to find area of circle?
The area of a circle can be found with the formula (pi)r^2
