given:
a cylindrical tank
diameter (or 2 radius) is 8 meters
d=2r=8m.........r=4m
height is h=3+m
each goldfish needs 2%5E3m of water
find volume:
V=+Area_+of_+base+%2A+height

V=%284m%29%5E2%28Pi%29%2A3m%0D%0A%0D%0A%0D%0A%7B%7B%7BV=16m%5E2%283.14%29%2A3m
V=150m%5E3 ........now divide volume by 2 to find the maximum number of goldfish you can put in
150%2F2+=75_+goldfish
