Question

how many litres of milk can hemispherical bowl of diameter 10.5 cm . hold ?

Answer 1

given,
radius is 5.25cm
and volume of hemisphere is 2/3pie r3
=2/3*22/7*5.25*5.25*5.25
=(44/21)*(9261/64)
=441*11/16
=4851/16
=303.1cc
and
one cc is equal to 0.001 liters
therefore hemisphere can hold 0.303 liters of milk

Answer 2

Volume of hemisphere = 2/3 π r³
= (2/3) × π × (10.5 cm / 2)³
= 303 cm³

Now, use the relation ==> 1 Litre = 10³ cm³

Volume = 303 cm³ × (1 Litre) / (10³ cm³)
= 0.303 Litres

Bowl can hold 0.303 litres of milk.
