If a transmitting antenna of height 105 ~m is placed on a hill, then its coverage area is

Step-by-step solution

aligned & Coverage area A = d ^2 and d = 2 R h & = ( 2 R h )^2= 2 R h & Here h=105 ~m , R=6.4 10^6 ~m & A=3.14 2 6.4 10^6 105 ~m ^2 & =314 2 64 10^6 105 10^3 ~m ^2 & =4220.6 ~km ^2=4224 ~km ^2 aligned
