Diameter of the conical pit = 3.5m
radius= 1.75m
height=12m
volume of cone= π h /3
= 3.14 * 1.75^2 * 12 /3
=115.39/3
= 38.46
volume of cone = 38.46 m^3
1= 1000 L = 1 kilolitre
hence ,
38.5 = 38.5 kilolitrs

Diameter of the conical pit = 3.5m (So, radius of the conical pit = 1.75m)
Height of the conical pit = 12m
Capacity of the conical pit is the volume of the conical pit.
Volume of the conical pit = (π x 1.75² x 12)/3 = 38.5m³
No, 1m³ = 1000 litre and 1000 litre = 1 kilolitre
So, 1m³ = 1 kilolitre
∴ 38.5m³ = 38.5 kilolitres
