Me ! what is the answer of this exercise?

 h = 15

Step-by-step explanation:

Volume (V) = Length (L) × width (w) × height (h)

1386 = 14 × 9 × (h - 4)

11 = h - 4

11 + 4 = h

15 = h

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
