# 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 :

Given,

Diameter of cylindrical bucket = 28 cm

Radius of bucket =

Height of bucket = 72 cm

Volume of water in bucket = πr^{2}h =

Length of rectangular tank = 66 cm

Width of tank = 28 cm

Let rise in water level in rectangular tank = h cm

∵ Volume of cylinder = Volume of rectangular tank

= 66 × 28 × h

⇒ h =
