For VHF signal broadcasting, \_\_\_\_ $\displaystyle \mathrm{km}^2$ of maximum service area will be covered by an antenna tower of height $\displaystyle 30$ m, if the receiving antenna is placed at ground. Let radius of the earth be $\displaystyle 6400$ km. (Round off to the Nearest Integer) (Take $\displaystyle \pi$ as $\displaystyle 3.14$)
