A frustum has end radii 4 cm and 6 cm. A cylinder of the same height has exactly the same volume as the frustum. What can you say about the cylinder's radius?

Question

Accepted Answer

a value between 4 cm and 6 cm. The frustum's volume lies between that of a cylinder of radius 4 (smaller) and radius 6 (larger) at the same height, so an equal-volume cylinder has radius between 4 and 6 cm.
