Question

a transmitting antenna has a height of 50 m. if radius of the earth is taken as 6250 km,find the area covered by it?

Answer 1

Answer:

1964.28 km²(approx)

Explanation:

d = √2Rh

R = 6250 km = 6250 x 1000 m

h = 50 m

Area(A) = πd²

⇒A = π2Rh

⇒A = 22/7 x 2 x 6250 x 1000 x 50

⇒A = 1964285714.285714‬ m²

⇒A = 1964.285714285714‬

⇒A = 1964.28 km²(approx)
