Find the total surface area of a right circular cone with radius 6cm and height 8cm.

Explanation

To find the total surface area of a right circular cone with a radius of 6 cm and a height of 8 cm, we can follow these steps:

### Step 1: Identify the given values
- Radius (r) = 6 cm
- Height (h) = 8 cm

### Step 2: Calculate the slant height (l)
The slant height (l) of a cone can be calculated using the Pythagorean theorem. In a right circular cone, the relationship between the radius (r), height (h), and slant height (l) is given by:
