Question

A cylinder and a cone both have a radius of 5 cm and a height of 12 cm.
Which statement is true about their volumes?

Select an answer

A.
The cone’s volume is larger.


B.
The cylinder’s volume is larger.


C.
Their volumes are equal.


D.
You cannot compare without π.

Answer 1

B. The cylinder’s volume is larger.

Reason: Cylinder V = πr^2h = π(5^2)(12) = 300π. Cone V = (1/3)πr^2h = 100π. So the cylinder is three times the cone's volume.
