Volume of a cylinder:
V = π(r^2)(h)
where
π = 3.14
r = radius
h = height
I think this is just trial and error. For instance, take r =2 and h=6:
V = π(2^2)(6)
V = 3.14 * 4 * 6
V = 75.36 m^3
This is one that satisfies the requirements. Just take a value of r and h from 2 and 7 and plug them in the formula.
hope this helps~ `u`
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
