Question 6 Surface Area And Volume Of Sphere Exercise 21.2
A vessel in the form of a hemispherical bowl is full of water. The contents are emptied into a cylinder. The internal radii of the bowl and cylinder are respectively 6 cm and 4 cm. Find the height of water in the cylinder.
Answer:
Radius of a bowl (R)= 6 cm (Given)
Radius of a cylinder (r) = 4 cm (given)
Let h be the height of a cylinder.
Now,
Volume of water in hemispherical bowl = Volume of cylinder
or h = 9
Therefore, height of water in the cylinder 9 cm.
