Calculate the height of a radio, television and telecommunications tower where the scale is 1:9 000; r = 100 mm; d = 6 mm and H = 750 m. Round the answer to first decimal, for example if the result is 123 then the answer is 123,0; if the answer 12,345 then the answer is 12,3 and if the result is 123,456 then the answer is 123,5. The height of the tower is:
