Question

A right circular cylinder has its height two times of its radius. It is inscribed in a right circular cone of diameter 10 cm and altitude 12cm and the axes of both the cylinder and cone coincide. The radius of the cylinder is\

Answer 1

Solution :-

let the diameter of cylinder be 2r

examining the cross section of the cone and cylinder we find two similar triangles.

Hence

=> 12-2r / 12

=> 2r/10 => r = 30/11

so volume of the cylinder

=> πr^2h

=> π× (30/11)^2 ×2r

=> π× (30/11)^2 × 60/11
