Answer: 1.5 cm rise in water level.
Step-by-step explanation:
Since we know that,
Diameter = 2 × radius
Here, diameter of cylinder = 18 cm and sphere = 9 cm
So Radius of cylinder = Diameter/2 = 18/2 cm = 9 cm
Radius of sphere = 9/2 cm = 4.5 cm
Volume of sphere =
Since volume of water displaced will be equal to volume of sphere, therefore
Volume of water displaced in cylinder = Volume of sphere
22/7 × 9 × 9 × h = 381.85
h = 381.85 × 7/22 × 1/81
h = 1.5 cm
Rise in water level is of 1.5 cm
