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

Imagine you have a waffle cone. The amount of ice cream needed to fill it up (just to the top) is the volume. The amount of waffle needed to make the cone, plus a circular lid to close off the top, is the surface area.

**The formula for the volume of a cone is V = 1/3πr²hThe formula for the surface area of a cone is SA = πr²** +

**πrs**

r is the radius of the circular base. h is the height of the cone. s is the slant height (the distance from the tip to the circular base, walking along the outside of the cone).

In these free math worksheets with answer keys, students will practice calculating volume. The formula for the volume of a cone is **V = 1/3πr²h**, where r is the radius of the cone and h is the height. **Remember:** The radius is half the diameter. Label all answers with the correct units: cubic in, cubic ft, cubic cm, etc.
