<u>Answer:</u>
The circumference of circle is 40.82 units.
<u>Explanation:</u>
The end points of diameter lie on circle. since the coordinates of end points of diameter may be evaluated using
d=
=
=
therefore d = 13 .
The formulae of circumference comprises the length of radius of circle, hence find the radius as half of diameter length r=d/2 = 13/2 = 6.5 ; circumference of circle =
= 2x3.14xr
= 13x3.14 units.
=40.82 units
