The diameter of a circle = 9 in

Radius of the circle (r) = 4.5 in

To find the circumference of the circle.

The circumference of the circle of radius r = 2πr

Now,

The circumference of the circle = 2×3.14×4.5 in [ taking π = 3.14]

= 28.26 in

leonid [27]

The expression for the number of segments drawn out of the n number of points in the circle is,
n² / 2 - n / 2
Substituting directly to the expression the number of points, n, which is equal to 8,
8² / 2 - 8 / 2 = 28
Thus, there are 28 segments that can be drawn from the points.
