A cylinder tank can hold 1, 416.93 dm³ of water. If it has a height of 5dm. What is the radius of the tank?

Vol of cylindrical tank =    1,416.93dm³
height                        =      5dm
V = πr²h    =    1,416.93 = πr² 5
           r² = 1,416.93/5π
           r =√(1416.93/5π          / π~ 3.14
               √90.25  ~ 9.5dm
