Question

A cylindrical bucket 28 CM in diameter and 72 cm high is full of water the water is emptied into a rectangular tank 66 M long and 28 cm wide find the height of the water level in the tank

Answer 1

Diameter of the bucket = 28 cmRadius = 14 cm Height of the bucket = 72 cm Volume of the water in the bucket = πr2h                                                  = 22/7 x 14 x 14 x 72                                                  = 44352 sq cm Length of the rectangular tank = 66 cm breadth of the rectangular tank = 28 cm Let the height of the water in the tank be 'h' cm Volume of the water in the rectangular tank = (66 x 28 x h) cu cmVolume of the water in the rectangular tank = Volume of the water in the bucket66 x 28 x h = 22/7 x 14 x 14 x 72 h = 22/7 x 14 x 14 x 72 x 1/66 x 1/28 h = 24 cmHeight of the water level in the rectangular tank = 24 cm.

Answer 2

hey
____________

as water from cylindrical tank is emptied into rectangular tank

•so volume of cylindrical tank = volume of rectangular tank

•volume of cylindrical tank = πr^2h

•volume of rectangular tank =l×b×h

πr^2h = l×b×h

for the full solution refer to the atatchment

hope helped
