The radius of a cylinder is 3.5 ft. The height is 14 ft. Find the surface area and volume of the cylinder to the nearest tenth of a foot.

Answer 1

the SArea of the outer cylinder wall is PI*2*r*h
if the ends are enclosed, then you have to add two ends, or 2x PI*2r

Answer 2

A=2*pi*r*h+2*pi*r^2 <-Use this formula for your problem. :)

Answer 3

and volume is pi r^2 h
