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.
