Updated: 12/23/2022

pi (3.1416, etc) (or 22/7) is the fundemental constant (given or a priori) in the relationship between the area of a circle and its radius or diameter).

i.e. area of a circle =Pi X R squared.

Likewise the circumference is Pi X D where D is the diameter of the circle.

How do you find the diameter and volume of a sphere if you have the surface area?

4*pi*radius2 = area radius = square root of (area/4*pi) diameter = 2*radius volume = 4/3*pi*radius3

How to find the surface area and volume of a sphere with a given radius.?

Given a sphere of radius r, Surface area = 4{pi}r2 Volume = (4/3){pi}r3

How can pi help you measure?

Pi is not a size. Pi is usually 22/7. Sometimes also 3,14. Pi is used to measure area and circumference of a circle, and the volume of sphere / tube. If there is no pi, then the area and circumference of circle, and the volume of sphere / tube will not be counted.

How is pi r squared used?

It is used to find the area of a circle as pi*radius2

What is pi used for in geometry?
