Curved surface area of a cone is `308\ c m^2`and its slant height is 14 cm. Find
(i) radius of the base and (ii) total surface area of the cone.

Explanation

To solve the problem step by step, we will find the radius of the base of the cone and then calculate the total surface area of the cone.

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