Solution

Radius (r) of hemispherical bowl = (10.5/2)cm = 5.25 cm

`"Volume of hemispherical bowl "= 2/3pir^3`

`=[2/3xx22/7xx(5.25)^3]cm^3`

= 303.1875 cm3

`"Capacity of the bowl "=(303.1875/1000)litre`

= 0.3031875 litre

= 0.303 litre (approximately)

Therefore, the volume of the hemispherical bowl is 0.303 litre.
