Find the curved surface area of a right circular cone whose slant height is 10 cm and base radius is 7 cm.

Answer:

**Solution:**

The shape of a cone is produced by stacking several triangles and spinning them around an axis. It has a total surface area and a curved surface area because it has a flat base.

Given slant height of the cone, l = 10 cm

Base radius, r = 7 cm

Curved surface area of the cone = π rl

= (22/7)×7×10 = 220 cm^{2}

**Hence the curved surface area of the cone is 220 cm ^{2}.**
