How to Find the Volume of a Sphere
Question
What is the volume of a sphere with a radius of 5 cm, as shown below?
Step-by-Step:
1
Start with the formula:
Volume = 4πr3 ⁄ 3
Don't forget: π is pi (≈ 3.14) and r3 = r × r × r (r cubed) and ⁄ means ÷.
2
Substitute the radius into the formula. In our example, r = 5.
Volume = 4 × π × 53 ⁄ 3
Volume = 4 × π × 125 ÷ 3
Volume = 4 × 3.14 × 125 ÷ 3
Volume = 523.3 cm3
Answer:
The volume of the sphere with a radius of 5 cm is 523.3 cm3.What Is a Sphere?
A sphere is a ball-shaped object. Each point on its surface is the same distance away from the center.The Main Parts of a Sphere
The radius is the distance from the center of a sphere to its surface. The diameter is the line that goes through the center of the sphere and joins two opposite points on the surface. It is twice the length of the radius.Who Discovered How To Find the Volume of a Sphere?
