A T.V. tower has a height of 150 m. The area of the region covered, the T.V. broadcast is (radius of earth = $6.4 × 10^6 m$) -
Answer & explanation
Correct answer: option 2
Area of the region covered for broadcasting
$= πd^2 = π(2hR)$
$= π × 2 × 150 × 6.4 × 10^6$
$= π × 300 × 6.4 × 10^6$
$= 19.2 × π × 108 m^2$
