which at r = 6 is 8pi(6)

=48pi

**Anonymous**, Thursday, January 24, 2008 at 11:04pmactually the answer is 64pi ft^3/ft.

can you figure out what you did wrong? thanks.

**Reiny**, Thursday, January 24, 2008 at 11:18pmNope, for the data you gave me the answer is 48pi

this is a very straighforward question,

to have an answer of 64 pi, perhaps you were to find the rate when r = 8.
