The area of the region covered by the TV broadcast by a TV tower of 100 m height is (Radius of the earth = `6.4 xx 10^6` m )

A

`12.8pixx10^8 km^2 `

B

`1.28 pi xx 10^3 km^2`

C

`0.64pi xx 10^3 km^2`

D

`1.28xx10^3 km^2`

Text Solution

Verified by Experts

The correct Answer is:
B
Area covered by T.V. signals
`A = 2pi` HR `= 2xx3.14xx100xx6.4xx10^6`
`implies A=1.28 pi xx10^3 km^2`
