A TvV tower has a height of 100 m. Find the area covered by the TV broadast, if radius of the earth is 6400 km.

A

`380xx10^(7)m^(2)`

B

`402xx10^(7)m^(2)`

C

`595xx10^(7)m^(2)`

D

`440xx10^(7)m^(2)`

Text Solution

Verified by Experts

(b) Area `=pir^(2)=pi=((2hR)^(1//2))^(2)`
Area `=2piRh=2xxpixx6400xx 10^(3)xx100=402 xx 10^(7)m^(2)`
