A tin can has a circular base and a volume of 80\pi cm^3. Express the diameter of the base of the can in terms of the height of the can.
Use h for the height of the can.
Diameter =

There's no formula, just figure it out.
-------------------
A tin can has a circular base and a volume of 80\pi cm^3. Express the diameter of the base of the can in terms of the height of the can.
------------------
Vol+=+pi%2Ar%5E2%2Ah
r%5E2+=+Vol%2F%28pi%2Ah%29
r+=+sqrt%28Vol%2F%28pi%2Ah%29%29
d+=+2sqrt%28Vol%2F%28pi%2Ah%29%29
--------------
for Vol = 80*pi cc:
d+=+2sqrt%2880%2Fh%29 cm
d+=+8sqrt%285h%29%2Fh cm
