MATH WORD PROBLEM HELP PLEASE

Mr. Wu needs to buy a right cylindrical fish tank that holds between 75 and 100 cubic meters of water. Using only these numbers: 2,3,4,5,6, and 7, identify a radius and a height for three different tanks that would fit Mr.Wu"s requirements. The same number may be used more than once.
Tank 1
r= ?m
h= ?m

Tank 2
r= ?m
h= ?m


Tank 3
r= ?m
h= ?m

asked by Kimbo
  1. v = pi r^2 h
    pi is about 3, so you want

    r^2 h to be somewhat more than 25
    since 24 = 6*2^2, let's try
    r=2, h=6
    pi * 4 * 6 = 75.39

    Now you can pick any other set of numbers that multiply similarly to about 25 or more.
