A cylindrical vessel of radius 7 cm contains water. A solid hemisphere of radius 6 cm is dipped into the water until it is completely immersed. The water level in the vessel will rise by

A.2.83 cm
B.2.94 cm
C.2.69 cm
D.3.01 cm
Answer and Feedback
Answer:B
Feedback:Let the rise in water be t cm.
Volume of water increased in cylinder = π × 7 × 7 × t ----(a)
Volume of hemisphere = 2/3 × π × 6 × 6 × 6 ----(b)
According to the question
a = b
∴ t = (4 × 36)/49 = 2.94 cm
