Solve 2 {3 [9 + 4 (7 + 5) - 4]}

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

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
