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 9 cm.

What is the approximate radius of the cylinder?

A.
4.5 cm

B.
5.1 cm

C.
12.9 cm

D.
25.8 cm

Answer 1

Volume of prism is 1/3 * area of base* height in this case base is square so we will put the area of square and volume of cylinder is pi * r^2 * height equate both the volumes u will surely get your answer

area of square = (side)^2 here side is 9 so can u determine the area?
