Question

How many litres of milk can a hemisphere bowl of diameter 10.5cm hold

Answer 1

volume of hemisphere
r=d/2
r=5.25
$\frac{2}{3} \pi {r}^{3} \\ \frac{2}{3} \times \frac{22}{7} \times 5.25 \times 5.25 \times 5.25 \\ 44 \times 1.75 \times 0.75 \times 5.25 \\ 303.1875$

the hemisphere can hold 303.1875 cm^3

Answer 2

Answer :

It can hold 0.303 litre of milk.

Step-by-step explanation :

Diameter of hemispherical bowl = 10.5 cm

Volume of hemisphere =  $\sf \frac{2} {3}$π r³

⇒ $\sf \frac {2} {3} \times \frac {22}{7} \times \frac {10.5}{2} \times \frac {10.5} {2} \times \frac {10.5} {2}$

⇒ 5.5 × 0.5 × 0.5 × 10. 5 × 10. 5 cm³

⇒ 303. 18 cm³

[ 1000 cm³ = 1 litre ]

⇒ 0.303 litre

Hence, the bowl can hold 0. 303 litres of milk.
