The product is rational because both V2 and V7 are rational numbers,

The product is irrational because both 2 and 7 are irrational numbers.

The product is rational because at least one factor is rational,

second option: product is irrational because both are irrational

Step-by-step explanation:

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
