The height and the slant height of a cone are 21 cm and 28 cm respectively. Find the volume of the cone

Explanation

To find the volume of the cone with a height of 21 cm and a slant height of 28 cm, we will follow these steps:

### Step 1: Identify the given values
- Height (H) = 21 cm
- Slant height (L) = 28 cm

### Step 2: Use the Pythagorean theorem to find the radius (R)
In a right triangle formed by the radius, height, and slant height of the cone, we can apply the Pythagorean theorem:
