Homework Statement
A frustum is made by removing a small cone from a large cone. The cones are mathematically similar.
(please see picture attached)
The large cone has base radius r cm and height hcm. Given that
volume of frustum/volume of large cone = 98/125
Find an expression, in terms of h, for the height of the frustum.
The Attempt at a Solution
By rearranging volume of frustum/volume of large cone = 98/125
we get:
volume of frustum = 1/3 x pi x r^2 x h x 98/125
Is that the right start? Do I need to work the volume of the frustum?
