# Volume and Surface Area of Spheres

**Free and premium, printable “Volume and Surface Area of Spheres Worksheets!”**

Imagine you have a basketball. The amount of air needed to fill it up is the volume. The amount of rubber needed to create the ball is the surface area.

**The formula for the volume of a sphere is V = 4/3 π r³The formula for the surface area of a sphere is SA = 4π r²**

In both equations, r is the radius of the sphere (the distance from the center of the sphere to a point on its surface).

**These formulas are harder to remember than most volume and surface area formulas, so it’s important to get a lot of practice.**
