A conical pit of top diameter 3.5m is 12m deep. What is its capacity in kiloliters? (Assume π = 22/7)

Given

Radius of cone (r) = 3.5/2 m

Height of cone (h) = 12 m

Find out

We have to find the capacity in kiloleters

Solution

Volume of cone = (1/3) × πr2h

On taking π=22/7

= (1/3) × (22/7) × (3.5/2) × (3.5/2) × 12

= (22 × 3.5 × 3.5 × 12) / (7 × 3 × 2 × 2)

= 38.5 m3

Capacity of conical pit in kilo liters:

1000 m3 = 1 liter

38.5 m3 = 1000 × 38.5 liters

= 38,500 liters

= 38.5 kilo liters

Answer

The capacity of the container is 38.5 kilo liters
