Question 5
How many liters of milk can a hemispherical bowl of diameter 10.5 cm hold?
$[Assume\pi =\frac{22}{7}]$

Answer 1

Radius (r) of the hemispherical bowl
$=\left(\frac{10.5}{2}\right)cm=5.25cm$

Volume of the hemispherical bowl $=\frac{2}{3}\pi r^3$
$=[\frac{2}{3}\times \frac{22}{7}\times (5.25{)}^3]c{m}^3$
$=303.1875c{m}^3$

Capacity of the bowl
$=\left(\frac{303.1875}{1000}\right)litre$
=0.3031875 litres = 0.303 liters (approximately)

Therefore, the bowl can hold 0.303 liters of milk.
