step-by-step explanation: given a sphere and a cylinder with same radius and height.
let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,
r = h.
now, the volume of the sphere will be
and the volume of the cylinder will be
therefore, we have
thus, ammie should have multiplied the volume of the sphere
