Question

The capacity of the cylindrical tank is
6280 litres . If it can filled
20 cylinders then find the height of celinders
given that the radius of cylinder is 5cm.​

Answer 1

GIVEN⇒ VOL. OF BIG CYLINDER = 6280 ,  20* VOL. OF SMALL CYLINDER = VOL. OF BIG CYLINDER  , RADIUS = 5 CM

TO FIND:  HEIGHT OF SMALL CYLINDER

PROOF : VOL. OF SMALL CYLINDER = 20*πR²H

                  6280 / 20 = 22/7*5²*H

                      H = 1.40 METRE
