Question

a cylindrical vessel of radius 77 cm is filled with water to the height of 80 CM if some more water is added to rise the height 200 cm find the increase in the volume of water in the vessel in litres

Answer 1

Answer:

radius=77cm

height=80cm

volume=π*r*r*h

            = π*77*77*80

now volume= π*77*77*200

increase in volume =π*77*77*200-(π*77*77*80)

                                  = π*77*77(200-80)

                                   = π*77*77*120

                                   = 22/7*77*77*120

                                     =2236080 cm³

                                    =2236080/1000 litres

                                     =2236.08 litres
