Diameter of the base of a cone is 10.5 cm and its slant height is 10 cm. Find its curved surface area.

Explanation

To find the curved surface area of the cone, we will follow these steps:

### Step 1: Find the radius of the cone
The diameter of the base of the cone is given as 10.5 cm. The radius (R) is half of the diameter.

\[ R = \frac{\text{Diameter}}{2} = \frac{10.5 \, \text{cm}}{2} = 5.25 \, \text{cm} \]
