A hemispherical tank has inner radius ...

A hemispherical tank has inner radius of 2.8m. Find its capacity in litres.

Text Solution

Verified by Experts

The inner radius of the hemispherical tank` =2.8 m`
Capacity of hemispherical tank `=2/3pir^3`
`=2/3xx22/7xx(2/8)^3`
`=>=2/3xx22/7xx2/8xx2/8xx2/8=137.984/3`
`=>45.99m^3=45990l`(1m=1000l)
Capacity of hemispherical tank `=45990 liters.`
