A TV broadcasting tower has a height of 100 m. How much population is covered by the TV Broadcast. If average population density around the tower is 1500 `km^(-2)` ? Radius of earth `=6.37xx10^6` m

Text Solution

Verified by Experts

h=100 m , R=`6.37xx10^6` m , P=`1500xx10^(-6) m^(-2)`
Population covered =`Pxxpid^2=Ppi^2Rh`
`=1500xx10^(-6)xx22/7xx2xx100xx6.37xx10^6=6xx10^6`
