What do you mean 'finding'? Pi is the ratip of the circumference to the radius of a circle.
2 pi r = circumference. 1/2 of that is pi x r. pi is 3.142
Area of a circle = (pi)r2 [Areacircle = pi time the radius squared.] Volume of a cylinder = (pi)r2h [Volumecylinder = pi times the radius squared times the height.] (This applies to a right circular cylinder. :)
2*pi*radius of the circle or diameter*pi where pi = 3.1416 or 22/7 and is usually rounded to 3.14.
pi * radius2 * height
3.14 is always the best 3 digit approximation of pi.
4-(4/3)+(4/5)-(4/7)+(4/9)-(4/11)....=pi There are no non-infinite serieses known for finding pi
The formula for finding area or mass of a cylinder is pi x radius^2density=massxvolume

2[4(radius)/3(pi)]
Circumference = pi x the diameter / pi x twice the radius / pi x square root of "area divided by pi". C = (pi) D C = 2 (pi) r C = 2 (pi) * [sq rt (A/pi)] r = radius D = diameter pi = 22/7 or 3.14
The formula for finding the circumference is C = Pi x D, where Pi = 3.1416 and D is the diameter. The Radius is one-half of the diameter., So, multiply the radius by 2 and then multiply by Pi.
