Question

how many litres of milk can a hemispherical bowl of diameter 10.5 CM hold

Answer 1

2425.5 cubic centi metre of milk.So 2.42 litres

Answer 2

Volume of hemisphere
$\frac{2}{3} (\pi)(r) {}^{3} \\ \frac{2}{3} \times \frac{22}{7} \times \frac{10.5}{2} \times \frac{10.5}{2} \times \frac{10.5}{2} \\ \frac{2}{3} \times 22 \times \frac{1.5}{2} \times \frac{10.5}{2} \times \frac{10.5}{2} \\ 22 \times \frac{1}{2} \times \frac{10.5}{2} \times \frac{10.5}{2} \\ 11 \times \frac{10.5}{2} \times \frac{10.5}{2} \\ 11 \times \frac{110.25}{4} \\ \frac{1212.75}{4} = 303.18 {cm}^{3}$
Volume of bowl is 303.18cm^3
