There is no formula for Pi, it cannot be represented by any formula. It is a fundamental constant.

use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi

There is only one formula for pi, which is the ratio of the circumference to the diameter of a circle.

It is the formula for finding the circumference of a circle which is the same as 2*pi*radius

the circumference formula uses pi and the formula is pi (3.14) times what ever the diameter is and that's one formula i know and I'm in fifth grade

The formula for the area of a circle is pi * radius squared. The circumference of a circle's formula is pi * diameter. NOTE: pi equals approx. 3.14

there is no s in PI

Any formula involving a circle will have "pi" in it. Area = pi* radius * radius Circumference = pi * diameter = pi * radius * 2 ( the diameter is just 2 times the radius) Quick way: A = pi r squared C = pi D

It is the formula used in finding the area of a circle which is pi times radius squared

The formula for circumference is 2(pi)r.Plug the numbers into the formula.You get (2)(pi)(4).8(pi) or, assuming pi is 3.14, 25.12.

Circumference of a circle = 2*pi*radius or pi*diameter

The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.

2*pi*radius or pi*diameter

2*pi*radius or pi*diameter

2*pi*radius or diameter*pi

The area of a circle = pi*r2

Because:- circumference/diameter = pi and when the formula is rearranged circumference = pi*diameter

the formula for a cylinder is pi *radius squared*height

To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi

The formula to find the circumference of a circle is Pi X D where D is Diameter and Pi is 3.1416.

The formula of percentage is pi. This is used in math.

d * pi or 2 * r * pi Where d is diameter and r is radius and pi = 3.14159
