Question 680312
Formula for the volume of a cylinder:

volume {{{V= pi*r^2*h}}}

Then we input the known values: {{{V=15000ft^3}}} and the cylindrical part is {{{h=30ft}}}


{{{15000ft^3 = pi * r^2 * 30ft}}}


{{{r = sqrt(15000ft^3/(pi*30ft))}}}


{{{r = sqrt(cross(15000)500ft^cross(3)^2/(pi*cross(30)cross(ft)))}}}


{{{r = sqrt(500ft^2/3.14)}}}


{{{r = sqrt(159.24ft^2)}}}


{{{r = 12.62ft}}}
