that is the radial angle, not SUM of interior angles.

If you want to calculate sum of interior angles for circle, first take a small bisector of the circle, call the angle delta phi (angle can be 0.00000001 degrees, i.e. very small). Then, since the sum of interior angles of a triangle is 180 degrees, which means one of the angles of the triangle must be 90 degrees.

Now, sum up all the 90 degrees through the whole circle, i.e. 90 + 90 + 90 + ...... add this for 100000000000000 times, you will get a very large number. Normally we say it is an infinite sum.

another math question:

Why they call it an xbox 360?
Because when you see it, you'll turn 360 degrees and walk away.


at first glance does not make sense right?


and its solution

Sum of Interior Angles = (n-2) × 180°

circle = approach infinite interior angles, so infinite degrees la
