Question

A hemispherical tank has inner radius of $1.05m$. Find its capacity in litres.

• A. $2425.51$
• B. $2657.15$
• C. $1236.5$
• D. None of these

Answer 1

Answer: (A)

$2425.51$

Capacity of tank $=$ volume of tank

Volume of hemispherical tank $=\frac{2}{3}\pi r^3$

Given $r=1.05m$

Capacity of the tank$=\frac{2}{3}\times \frac{22}{7}\times 1.05\times 1.05\times 1.05$

$=2.4255m^3=2425.5litres$
