A conical pit of top diameter 3.5 m is 12 m deep. What is its capacity in kilolitres?

Text Solution

Verified by Experts

Volume of a cone can be given as, `V = 1/3piR^2h`
Here, `R = d/2 = 3.5/2m`
`h = 12m`
So, `V = 1/3**22/7**3.5/2**3.5/2**12 = 11**3.5= 38.5m^3`
Now, we know,
`1m^3 = 1000litre=>1m^3 = 1 kilolitre`
so, capacity of given come will be `38.5` `kilolitres.`
