Which of the following pairs of points are on the same vertical line? a (–3, –9) and (–3, 4) b (–3, –9) and (3, –9) c (3, 9) and (–3, –9) d (–3, –4) and (–4, –3)

answer: the answer is (b) amie should have multiplied

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
