If the height of a cone is doubled while keeping the radius the same, how does the volume change?
Show answer & explanation
Correct answer: A
Explanation
The volume of the cone is V = 1/3 × πr²h.
Here, the radius r remains the same, while the height h is doubled.
Therefore, the new volume V' = 1/3 × πr² × 2h.
V' = 2V.
The volume will double.
