Question 1116306
Volume of water in the bowl
{{{(1/2)(4/3)pi*7^3}}}


{{{(2/3)*7^3*pi}}}



If y is the height of the water filled into the cylinder, then
{{{y*pi*5^2=(2/3)*7^3*pi}}}


{{{y=(2*7^3)/(5^2)}}}
Compute this.  Question says that this height is {{{3/4}}} of the cylinder filled, so for the height of the cylinder you are looking for {{{(4/3)y}}}.
