Question 401504


given:
 a cylindrical tank 
diameter (or 2 radius) is 8 meters

{{{d=2r=8m}}}.........{{{r=4m}}}

height is {{{h=3 m}}} 

each goldfish needs {{{2^3m}}} of water

find volume:

{{{V= Area_ of_ base * height}}}


{{{V=(4m)^2(Pi)*3m


{{{V=16m^2(3.14)*3m}}}

{{{V=150m^3}}} ........now divide volume by {{{2}}} to find the maximum number of goldfish you can put in

{{{150/2 =75_ goldfish}}}
