Question 135093
Volume of a cylinder:  {{{V[cyl]=pi*r^2h}}}


Volume of a cube: {{{V[cube]=s^3}}}


Volume not taken up by cylinder: {{{s^3-pi*r^2h}}}


Radius of cylinder = 10 (half the diameter)


Height of cylinder = 15 (given)


Side of cube = 20


{{{8000-pi*1500=3287.61}}}, approx.


{{{3287.61/8000=.41}}}, so 41%
