Question

How many liters of milk can a hemispherical bowl of diameter 10.5 cm hold?

Answer 1

Radius of the hemispherical bowl, r = $\frac{10.5}{2}$ cm = 5.25 cm
Volume of the hemispherical bowl =$\frac{ 2}{3}\pi$ r3

= $\frac{2}{3}$ × $\frac{22}{7}$ × 5.25 cm × 5.25 cm × 5.25 cm
= 303.1875 cm3

$= \frac{303.1875 }{1000}$ (1000cm3 = 1L)
= 0.3031875 liters
= 0.303 liters
Therefore, the volume of the hemispherical bowl is 0.303 liter.
