Find the curved surface area of a cone with base radius 5.25cm and slant height 10cm.

Explanation

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

### Step 1: Identify the formula for the curved surface area of a cone.
The formula for the curved surface area (CSA) of a cone is given by:
\[ \text{Curved Surface Area} = \pi r l \]
where \( r \) is the radius of the base and \( l \) is the slant height.
