Circumfrence of a circe = 2 pi r
r = 15 / 2 (since the circle is inscribed in the square it's diameter is 15)
So cicumfrence = 2 pi 15/2
= 15 pi units

the diameter of a circle inscribed in a square = the side of the square or 15. The circumference is pi*d or 15pi=47.12

If a circle is inscribed in a square, the radius is half of the side, so r = 7.5
Use the formula: C = 2(pi)r, and you get 15pi.

The ratio of circumference to perimetre of square is =Pi /4 which is 78.54% .
So perimetre = 4 x 15=60 units
circumference = .7854 x 60=47.123 units

side of square= 15 = diameter of circle
so, circumference = pi * d = 3.14 * 15 = 47.1 (appreox)

15 pi
diameter=15
circumference=2XpiXr
=pi*d
