Volume & Surface Area of Spheres

Volume tells us the amount of space inside a given 3D shape. Surface area tells us the area of the surface of a 3D shape.
Think of it in terms of an apple. The volume is the total amount of apple, and the surface area is the amount of skin on the apple.
The only thing we need to know in order to get both the surface area and volume is the radius. The radius of a sphere is the distance from the center of the sphere to its surface.Once we know the radius, we can calculate the volume and surface area of a sphere using the following formulas:Try some problems out with our calculator or scroll down to learn more about how to find the volume and surface area of a sphere.

Recap 🧒 How to Find the Volume and Surface Area of a Sphere

Step 1. Determine if you’re solving for volume (V) or surface area (SA).

What are you trying to solve for?
We're looking for the volume, or the total amount of space inside the sphere, which is like the total amount of apple.

Step 2. Find the radius of the sphere.

The radius is the distance from the center of the sphere to the surface.

Step 3. Calculate the volume with the radius.
