Question

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

Answer 1

cylindrical bucket's diameter= 28 cm, radius=14cm
height=72 cm
rectangular tank's length =66 cm
breadth= 28 cm
as per question,
volume of water in cylindrical bucket=volume of water in rectangular tank
$\Pi r^{2}h=lbh$
$\Pi (14{)}^2\ast 72=66\ast 28\ast h$
$h=24cm$
