Question 212122
 cylinder has a volume of 75 pi cm cubed, the radius and height are both whole numbers, 
given this data, the radius of the cylinder must be greater than the height
:
The formula:
{{{pi*r^2*h}}} = V
:
{{{pi*r^2*h}}} = {{{75*pi}}}
divide both sides by {{{pi}}}
r^2*h = 75
h = {{{75/r^2}}}
choose a value for r which gives an integer value for h.
r = 5, then h = 3; the only solution that satisfies
