The radius of the base of a right circular cone is 9 cm and its slant height is 49 cm. Find the curved surface area of the cone.

Question

Accepted Answer

The formula for the curved surface area (CSA) of a right circular cone is given by CSA = πrl, where r is the radius of the base and l is the slant height.

Given:  
r = 9 cm  
l = 49 cm

Using π ≈ 22/7,  
CSA = (22/7) × 9 × 49  
= (22/7) × 441  
= 22 × 63  
= 1386 cm²

Therefore, the curved surface area of the cone is 1386 cm².
