Question

The volume of a cylinder is 225π cm³ and its height is 9 cm.

What is the length of the cylinder's radius?

Enter your answer in the box.

cm

Answer 1

5cm

Explanation:

Given data

volume = 225π cm³

Height= 9cm

r= ???

Volume of cylinder

v=πr^2h

substitute

225π= π*r^2*9

225= r^2*9

r^2= 225/9

r^2= 25

r= √25

r= 5cm

Hence the radius is 5cm
