Use any of the digits 1, 2, 3, 4, 5, 6, 7, 8, or 9 no more than once so that (-)^2 + (+)^3 has: a. the greatest possible answer

b. the lowest possible answer

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
