Question

A cylinder and a rectangular prism have the same volume and same height. The base of the prism is a square with side length 7 cm.

What is the approximate radius of the cylinder?

A. 4.0 cm

B. 3.5 cm

C. 2.2 cm

D. 1.5 cm

Answer 1

if they have the same volume and height then the bases would have to have the same area, and the base of the prism would be 49, we know that the area of the circle is \[\pi r ^{2}\] so just inverse it find the square root of 49, (7) and divide it by pi which is roughly 2.2
