AnswerTo the following subject of 1.08×10 in standard form you have to calculate the radius in yet to find the perimeter
0.8888888 = 8/9
2.8888888 = 26/9
-2.888888 = -26/9
One way to do this is use the fact that the exterior angles of all polygons add up to 360 degrees
So an exterior angle of a regular octagon = 360 / 8 = 45 degrees.
So each interior angle = 180 - 45 = 135 degrees
so total measure of all angles in octagon = 8 * 135 = 1080 degrees
