Find the volume of a cylinder of height 6" and base with circumference 16 pi ".

Question

mertsj · Answer

The volume of a cylinder is the area of the base multiplied by the height.  To find the area of the base, you need to know the radius of the base. 
Since you know the circumference of the base and since C=2pi(r) you can find the radius.  
Can you do that?

anonymous · Answer

The first equation you can solve is 
Circum = pi 2r 
16pi = pi 2 r, 
16 = 2 r
r = 8

Vol = pi (8 sqd) 6
Vol = pi (64) (6)
Vol = 384pi

Do you understand how the equation works, now that I broken it down for you?
Try applying this to the other problem you are working on and see if you can do one on your own.
