Answer:

Number of days = 0.999 days.

Step-by-step explanation:

Given : A housing society consisting 5500 people needs 100l of water per person per day the cylindrical supply tank is 7m high and has diameter 10m.

To find : How many days will the water in the tank last for the society?

Solution :

Diameter of tank= 10 m

Radius of tank = 5 m

Height = 7 m

Now, the volume of the tank is

V= π * r² * h

V= π * 5² * 7 m³

V= 175π m³

V= 175π * 1000 litres

V= 175000π litres

V= 175000 * 3.14 litres ( π = 3.14 )

V= 549500 litres

Here, the daily requirements of water is

= 5500 * 100 litres

= 550000 litres

Hence, the tank will last for

d=capacity of tank/ daily requirement

d=549500/550000

d= 0.999 days

Therefore, Number of days = 0.999 days.
