Question

How does the volume of an oblique cone change if the height is reduced to 2/5 of its original size and the radius is doubled?

Answer 1

Well, what do you think happens?

Answer 2

Think about the volume of a cone

Answer 3

let the formula of a generic cone be

V = (1/3)(pi)r^2 * h
where r is the radius and h is the height. since the radius is being doubled, and the height is being reduced to 2/5 of its original size, replace r with 2r and h with (2/5)h in the formula, and see what happens to the value of V
