Okay, first thing, let's draw a diagram.
00:02
Here is my circle.
00:05
Let's say down here is minus 2, minus 2, and up here somewhere is 5 .4.
00:17
So here is my diameter.
00:20
And the first thing we do is find the circle center.
00:24
That's the midpoint between those two coordinates.
00:27
It's called it m.
00:28
And to find m, all i do is midpoint formula.
00:33
So add up the x coordinates.
00:34
So, i'll add up the x coordinates.
00:35
So, so minus 2 plus 5 divided by 2 and add up the y coordinates minus 2 plus 4 divided by 2.
00:46
So that will be 3 over 2 and 2 over 2 1.
00:53
So that means then this center of the circle 3 over 2 1...
