Well I believe that Archimedes measured the Circumference of a circle then divided by the diameter. He then realized through simple algebra that if C/d = pi then d*pi = C

Area = (pi) (R)2
What is the formula used to find areaof a circle?
Area in square units = pi*radius2
What formula is used to find the volume and the surface or a cylinder?
V=Pi*R2*H
What formula is used to find the circumference when you know the radius?
Circumference=2*pi*radius
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 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).
The formula d times pi is used to find what measurement of a circle?

What is the constant used in the formula to find the area of a circle?
You are thinking of pi.A = (pi)r^2
What is the formula used to find the circumference when you know the radius?
A=pi times r times r
Find the area of a cylinder?
To find the area of a cylinder a simple formula used is A=2(pi)r2 +2(pi)rh with; R being the radius of the circle and H being the height of the cylinder. the formula can also be translated as; 2(pi)rX[r+h]
What is the formula of percentage?
