    Water in the tank will last for 1 day.

    Step-by-step explanation:

    Step 1:

    Given diameter of tank = 10m, so radius = 5m,

    height of tank = 7m

    Number of people in society = 5500, number of L per day per person = 100L

    Step 2:

    Calculate total liters of water required

    ⇒ Total L required in the society = 5500 × 100 = 550,000 L

    Step 3:

    Calculate volume of water in tank in 1 day

    ⇒ Volume of cylinder = πr²h = 22/7 × 5 × 5 × 7

    ⇒ Volume = 22 × 25 = 550 m³

    ⇒ Volume = 550,000 L (since 1 m³ = 1000 L)

    Step 4:

    Calculate number of days water will last

    ⇒Number of days = Total water required/Volume of tank

    = 550,000/550,000

    ⇒ Number of days = 1
