T.V. transmission tower at a particular station has a height of 160 m.
(a) What is the coverage range ?
(b) How much population is covered by transmission, if the average population density around the tower is 1200 per `km^(2)` ?
(c ) What should be the height of tower to double the coverage range

Explanation

Population covered = (population density) `xx` (area covered) `= (1200) xx (pid^(2))`
`= (2400piRh) = 2400xx3.14 xx 6.4 xx 10^(3)xx 0.16= 77.17 lac`
