the new volume will be 144 π cubic inches
the volume of the cylinder using the formula V = πr^2h, where V is volume, r is the radius, and h is the height.
so quadruple the height in order to find the new height
calculate the new volume using the new height while keeping the radius the same
the original volume: V = π(3/2)^2 * 8 = 36π in^3
now the new height after quadrupling: 8 * 4 = 32 in
final new volume: V_new = π(3/2)^2 * 32 = 144π in^3
correct me if I’m wrong ^^
