Question

A cylindrical bucket $28cm$ in diameter and $72cm$ high is full of water. The water is emptied into a rectangular tank $66cm$ long and $28cm$ wide. Find the height of the water level in the tank.

Answer 1

Volume of water in bucket $=$ Volume of water in tank

$\Rightarrow \pi r^{2}h=L\times B\times H$
$\Rightarrow \frac{22}{7}\times 14\times 14\times 72=66\times 28\times H$
$\Rightarrow H=\frac{44352}{66\times 28}=24cm$
