Describe what happens to the volume of a cone when the radius is doubled while its height is halved. The volume is
Question
Solution 1
The volume of a cone is given by the formula V = 1/3πr²h, where r is the radius and h is the height.
If the radius is doubled, the new radius is 2r. If the height is halved, the new height is h/2.
Substituting these values into the formula gives the new volume as V' = 1/3π(2r)²(h/2).
