A triangle has sides that measure

To determine

**To find: **The exact volume of the solid of revolution formed when the triangle is rotated.

Explanation

**Given:**

A triangle has sides that measure 15 cm, 20 cm, and 25 cm. A solid is formed when the triangle is revolved about the side of length 15 cm.

**Formula used:**

The volume of the right circular cone is

**Calculation:**

When the triangle is rotated about its 15-cm side, a right circular cone is formed with altitude 15 in and base radius 20 cm as shown below

Thus we have

Substitute the known values in the formula,
