Solution

The correct option is A 718670
Given, radius, $r = 7 m$

Volume of hemispherical vessel $= \frac{2}{3} π r^{3} = \frac{2}{3} \times \frac{22}{7} \times 7^{3} = 718.666 ≅ 718.67 m^{3}$

Given, $1 m^{3} = 1000 l i t r e s$
$∴$ Volume of hemispherical vessel (in litres)
$= 718.67 \times 1000 litres = 718670 litres$
