The volume of a cylinder is 980 in.407207020200_files/i0220001.jpg. The height of the cylinder is 20 in. What is the radius of the cylinder?
Express your answer to the nearest hundredth.

I'm sorry you didn't proofread your post and gotten rid of the extraneous garbage.
V=πr2h
980 = 3.14 * r^2 * 20
980 = 62.8 * r^2
980/62.8 = r^2
15.6051 = r^2
3.95 = r 
Find the volume of the cylinder. Use 3.14 for pi when the radiusis3 and the height is 12
