The formula for volume of a sphere is given as:
V = 43πr3
Where V is the volume and r is the radius.

volume of a sphere

Example Problems

Problem 1:
What is the volume of a sphere with a radius of 10?
Solution:
1.) Plugging the radius into the volume formula, we get:
V = 43πr3
V = 43π(103) = 40003π
2.) The volume of the sphere is 40003π.

Problem 2:
What is the volume of a sphere with a diameter of 10?
Solution:
1.) Dividing the diameter by 2 to find radius, we get:
10/2 = 5
r = 5
2.) Plugging the radius into the volume formula, we get:
V = 43πr3
V = 43π(53) = 5003π
3.) The volume of the sphere is 5003π.
