Question

If the height , h , of a right circular cone is 5 times the radius, r of its base, express the volume V of the cone as a function of h. V(h)=

Answer 1

Using the letter r to represent the radius length, the height, h, would be 5r according to your statement.

Volume of a cone is (1/3) (pi) r² h . Sub in h= 5r to obtain (1/3) (pi) r² (5r) and simplify.
