For a regular polygon, let r and R be the radii of the inscribed andthe circumscribed circles. A false statement among the following isThere is a regular polygon with `r/R=1/(sqrt(2))`(17)There is aregular polygon with `r/R=2/3`(30)There is aregular polygon with `r/R=(sqrt(3))/2`(47)There is aregular polygon with `r/R=1/2`(60)

Answer» `cos pi/n = r/R`
`n=1; r/R= -1`
`n=2 ; r/R=0`
`n=3 ; r/R=1/2`
`n=4 ; r/R = 1/sqrt2`
`n=5 ; r/R= cos 36^@`
`n=6 ; r/R = sqrt3/2`
option 2 is correct
