Question 38271: If the circumference of a right circular cylinder is 18pi(don't have pi on the keyboard) and the height of the cylinder is 8, then find the volume to the nearest tenth. I found the radius of the circle to be 9, but when i find the volume of the cylinder i get 2287.1, which isn't one of my choices. Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! The volume of a right circular cylinder is
V = (pi)(r^2)h
If the circumference is 18(pi), then yes, the radius is 9.
Plug in what we know and get...
V = (pi)(9^2)(8)
V = 648(pi)
V = 2035.8
You must have calculated incorrectly.
