Question

If the radius of a cylinder is doubled and the height is tripled, what happens to the volume? A) It is multiplied by 6. Eliminate B) It is multiplied by 12. C) It is multiplied by 18. D) It is multiplied by 32.

Answer 1

A. Imagine the circle has a radius of 3 and height of 9. 3 x 9 = 27/3 is 9. If radius is doubled that’s 6 and height is tripled would make it 27. So 6 x 27 is 162 divided by 3 is 54 and 9 x 6 is 54
