To find the volume of a cone, you can use the formula V = (1/3) * π * r^2 * h, where r is the radius of the base and h is the height.
For a cylinder, the volume is calculated using the formula V = π * r^2 * h.
Since the volumes of the cone and cylinder are equal, we can set them equal to each other:
(1/3) * π * r^2 * h = π * R^2 * H
Simplify by cancelling π and multiplying by 3:
r^2 * h = 3 * R^2 * H
Now we can see that if we let R = 15 and H = 4, then r = 5 and h = 12 because 5^2 * 12 = 3 * 15^2 * 4.
Therefore, the correct values for the radius and height of the cone are:
radius of the cone = 5; height of the cone = 12
