Question 936019
diamter (d) = 14 inches
 radius (r) = d/2  = 14/2 = 7 inches
height (h)= 6 inches
 capacity of the tank = volume of the tank
volume of cylinder  (tank) =  pi*r^2*h
              capacity of the tank (V) = pi*7^2*6
                                                  (pi=22/7 = 3.14)
                  {{{V= (22/7) *49*6}}}
                     {{{V= 22*7*6}}}
                        V= 924 cubic inches'
one gallon equals 231 cubie inches
      hence capacity of tank in gallons  =  924/231  
                                         =4
Result : Capacity  = 4 gallons
