Question

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

Answer 1

Let the height of the water level raised $=xcm$
$\pi r^{2}h=l\times b\times x$
i.e. $\frac{22}{7}\times 14\times 14\times 72=66\times 28\times x$
$x=24cm$
