Question

Curved surface area of a cone is 308 cm² and its slant height is 14 cm. 

Find 

(i) radius of the base, and 

(ii) total surface area of the cone.

Answer 1

If Curved surface area of a cone, πrl = 308 cm² . 

height, h = l = 14 cm. 

Then, (i) r = ?, 

(ii) T.S.A. = ? 

(i) CSA of a Cone = πrl
