The radius of the base of a right cone is 35 cm and its height is 84 cm. Find : curved surface area

Explanation

To find the curved surface area of a right cone, we can follow these steps:

### Step 1: Identify the given values
- Radius of the base (r) = 35 cm
- Height of the cone (h) = 84 cm

### Step 2: Calculate the slant height (L)
The slant height can be calculated using the Pythagorean theorem:
