Volume of a Sphere

How to find the volume of a sphere? The formula for volume of a sphere will help you calculate the volume of a sphere. The volume of a sphere formula is given below. In calculating the volume of a sphere, we measure the radius of the sphere. The radius of a sphere is the distance between the center of the sphere and the surface of the sphere. No matter where you measure the radius of the sphere the distance between the center point of the sphere and any point on the surface of the sphere is the same. In the volume of a sphere calculation, we again use the mathematical entity 'pi'. Using the formula for the volume of a sphere, finding the volume of a sphere is easy and fun.

What is the formula for the volume of a sphere?

Below is the formula for the volume of a sphere. It is sometimes called the volume of a sphere equation. In calculus, proof for the volume of a sphere is also not difficult to do and the calculus proof for the volume of a sphere will be discussed in other section of this website. Below is the volume of a sphere formula.

Examples of how to find the volume of a sphere:

1. What is the volume of a 3 inch sphere?
• The volume of a sphere with radius of 3 inches is: 4 x 3.14159265 x 3 x 3 = 36 x 3.14159265 or 36
2. If you double the radius of a sphere, is the volume affected?

If you double the radius of a sphere then your new radius is effectively 2r. That means the new volume of the sphere is:

= (4/3) x  x (2r) ³

= (32/3)  r ³
