Question

A cylindrical vessel with internal radius 5 cm and height 10.5 cm is full of
water. A solid cone of base diameter 7 cm and height 6 cm is completely
immersed in the water. Find the volume of water left in the cylindrical vessel​

Answer 1

Answer:

volume of cylinder

πr²h

r=5cm

h10.5cm

22/7 ×5×5×10.5

22×37.5

825cm³

volume of cone

1/3πr²h

r=D/2=7/2

h=6

1/3 22/7 ×7/2 ×7/2 ×6

1/3 ×11×7/2 ×6

11×7/2 ×2

11×7

77cm³

volume of water left=volume of cylinder-volume of cone

825-77

volume of water left in the cylinderical vessel=748cm³
