Geometry and Trigonometry practice question

Answer: 4

Volume = πr²h. With the same height, the ratio is (4²)/(2²) = 16/4 = 4.

Common wrong answers

If you answered 2

2 is the ratio of the radii. Volume depends on the radius SQUARED, so the ratio is 2² = 4.

If you answered 8

8 would be the ratio if the height had doubled too (2³).

If you answered 16

16 is 4², the square of A's radius alone; divide by B's 2² = 4.
