Question

How many litres of milk can be hemispherical bowl of diameter $10.5cm$ hold?

• A. $0.303$ lit
• B. $0.323$ lit
• C. $1.303$ lit
• D. $0.603$ lit

Answer 1

Answer: (A)

$0.303$ lit

Diameter of the bowl $=\frac{Diameter}{2}=\frac{10.5}{2}=\frac{21}{4}$

Volume of a hemisphere $=\frac{2}{3}\pi r^3$

$=\frac{2}{3}\times \frac{22}{7}\times \frac{21}{4}\times \frac{21}{4}\times \frac{21}{4}$

$=303.2{cm}^3$

One litre of milk requires $1000{cm}^3$ of volume.

Hence in $303.2{cm}^3,\frac{303.2}{1000}=0.303$ litres of milk can be filled.
