Question

the inner curved surface area of a well is 220m and radius of its base 5m. find its hight

Answer 1

Well : Cylinderical in shape.
Let the height be 'h'.
   CSA of the well = 2πrh
                       220=2π×5×h
                  220×7     
                -----------=h
                 2×22×5   
                     1540
                     ------ =h
                      220
                      7=h
∴The heigth of the well is 7m.
