Where does pi r squard come from?
Pi r squared comes from the formula to find the area of a circle.
What is the formula to find the area of a circle with the radius given?
A = pi x radius squared where pi = 3.14
What is formula to find diameter of circle when circumference is known?
pi = C / d C = pi times d d = C / pi
What formula is used to find the diameter when you know the circumference?
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
What is the equation to find the circumference of a circle?
The formula is pi x the diameter of the circle, which is also pi x (2 x the radius) C = pi * D C = pi * 2r
What is the formula to find circumference when you are given the radius?
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
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 formula for the circumference of a circle?
Circle's circumference = 2*pi*radius or diameter*pi
What is the formula to find a area of a circle?
pi times the square of the radius A=pi*(r^2)
What is the formula doe for the area of a circle?
The formula to find the area of a circle is: A = pi * r2
What is the formula to find the circumference if the diameter is known?
Times it by pi
What is the formula to find the volume of a cylender?
pi * radius2 * height
Where does pi r squard come from?
Pi r squared comes from the formula to find the area of a circle.
What is the formula to find the area of a circle with the radius given?

What is the formula to find the cercumfrence?
2πr (2 times pi times the radius, or pi times the diameter)
Formula to find area of circle?
The area of a circle can be found with the formula (pi)r^2
What is formula to find diameter of circle when circumference is known?
pi = C / d C = pi times d d = C / pi
