Question

A housing society consisting of 5500 people needs 100 L of water per person per
day. The cylindrical supply tank is 7 m high and has a diameter 10m. For how many
days will the water in the tanks last for the society?​

Answer 1

Answer:

volume of the cylinder + people and liters of water

Answer 2

Answer:

Step-by-step explanation:

answer is 1 day

hope it's helps!!!

pls give me brainliest answer

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 * 22/7 litres ( π = 3.14 )

V= 550000 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=550000/550000

d=1 day

Therefore, Number of days = 1 day.
