Question

In a hospital used water is collected in a cylindrical tank of diameter 2 m and height 5 m. After recycling, this water is used to irrigate a park of hospital whose length is 25 m and breadth is 20 m. If tank is filled completely then what will be the height of standing water used for irrigating the park.

Answer 1

Answer:

The height of standing water used for irrigating the park is 0.0314 m.

Step-by-step explanation:

Given :

Height of a cylindrical tank ,h = 5 m

Length of a hospital park, l = 25 m

Breadth of a hospital park, b = 20 m

Diameter of cylinder tank = 2 m

Radius of cylinder tank ,r = 2/2 = 1 m

Let H be  height of standing water.

Volume of cylindrical tank = Volume of water in park

πr²h = l × b × H

π × 1 × 1 × 5 = 25 × 20 × H

5π = 500H

5 × 22/7 = 500 H

H = (5 × 22)/ 7 × 500

H = 22 /700

H = 0.0314 m

Height of standing water = 0.0314 m

Hence, the height of standing water used for irrigating the park is 0.0314 m.
