Answer by rcmcc(152)   (Show Source): You can put this solution on YOUR website!

substitute the volume into the equation to get the revise equation

because there is a on the top and bottom they cancel to give the equation

at this stage you can simplify the brackets

now you can solve the equation for r

The radius of the spherical tank is 2m
