Question

A TV tower has a height of 100 m. The average population density around the tower is 1000 per

k m^{2}

. The radius of the earth is

6.4 \times 10^{6}

m. The population covered by the tower is

Options:

A . 2× 106

B . 3× 106

C . 4× 106

D . 6× 106

Answer: Option C
:
C
Population covered =

2 π h R \times

Population density

= 2 π \times 100 \times 6.4 \times 10^{6} \times \frac{1000}{(10^{3})^{2}} = 4 \times 10^{6}
