All right, so we have a 120 degree angle that is measured.
00:07
If a circle is centered at the vertex of the angle, then the arcs up tended by the angles raised is blank times as long as one 360th of the circumference of the circle.
00:21
All the way around the circle is 360.
00:27
So if we're going to do one 360th, that would be like this right here.
00:34
And so that means there's 360 of these to micle all the way around the circle.
00:40
But we have to get to 120 degrees, so that means there's going to be 120 of these, because this is one degree each time.
00:48
So then that's 120 times as long as 1 ,360th.
00:57
Then the second part says a circle is centered at the vertex of the angle.
01:03
And 1 ,360th of the circumference is 0 .03 centimeters.
01:08
So this little distance here is 0 .03, and that's for 1 degree.
01:14
Well, then, what is this 120 degree angle? well, you have to take 120 times 0 .03, and 120 times 0 .03 is going to be 3 .6 centimeters...
