Question

A TV transmitting antenna is 75 m tall. How much maximum distance and area cover by it? Radius of Earth = 6.4 × 106 m.

Answer 1

Height of antenna h = 75 m
Radius of the Earth R = 6.4 × 106 m
(i) ∴ Maximum distance of transmitting

(ii) Maximum area covered by transmitting
A = πd2
A = π (2Rh)
A = 3.14 × 960 × 106 m2 = 3014 × 106 m2
A = 3014 km2
