If the height of the transmitting tower is increased by 30 % , then the area covered by it increases by

Options

  1. A10 %
  2. B21 %
  3. C30 %
  4. D60 %

Correct answer

C. 30 %

Step-by-step solution

Area covered by a transmission tower of height h is aligned & A=2 R h & A h aligned So, if height is increased by 30 % , area of coverage also increase by 30 % .
