Question

The diameter of a right circular cone is 14 m and its slant height is 10 m. Find its curved
surface area

Answer 1

Step-by-step explanation:

Given:- Diameter of a cone = 14 m

Radius (r) of a cone =14 / 2 = 7 m.

Slant height (l) of a cone = 10 m

Curved Surface area of a cone = πrl sq. unit

$= \frac{22}{7} \times 7 \times 10 \: \: \: sq.m$

$= 220 \: \: \: sq.m$

Curved Surface area of a cone is 220 sq. m.
