A TV tower has a height of 150 m. The area of the region covered by the TV broadcast is (radius of earth `=6.4xx10^(6)m`)

A

`9.6 pixx 10^(8) m^(2)`

B

`19.2 pi xx 10^(8) M^(2)`

C

`19.2 pi xx 10^(10) m^(2)`

D

`1.92 xx 10^(3)km^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`A = 2 piRH = 2 (pi) (6.4 xx 10^(6)) (150)m^(2)`
`= 1.96pi xx 10^(3) km^(2)`
