Question

The CSA of a cone is 308 sq cm and its slant height is 14 cm. Find its volume.

Answer 1

Given ,
CSA of cone - 308 sq cm
slant height - 14 cm
find ,
volume
CSA of cone = πrl
308 = 22/7 × 14 × r
308÷44
7 = r
volume of cone = 1/3πrsqh
1/3 × 22/7 × 7 × 7 ×14
1/3 × 22× 7 × 14
1/3 × 2156
718.6 is volume of cone
