Question

If the radius of this cylinder is doubled, its volume will be.. A. twice as much. B.four times as much. C.eight times as much

Answer 1

Answer: B. four times as much.

Explanation:

Answer 2

The volume of a cylinder is expressed as:

Volume = πr²h

where r is the radius of the base and h is the height of the cylinder. If the r is doubled then,

Volume = π(2r)²h
Volume = 4πr²h

Therefore, the correct answer is option B. The volume is four times as much the original volume.
