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

A

0.1

B

0.21

C

0.3

D

0.6

Text Solution

Verified by Experts

The correct Answer is:
C
Area covered by a transmission tower of height h is
`A=2piRh`
`rArr" "Aproph`
So, if height is increased by 30%, area of coverage also increases by 30%.
