Weby = v ± r 2 − x 2 + 2 x u − u 2. This will tell us what y is. There are actually two possible y values for each x. You can see this if you look at a circle. It should also be noted that even though this is correct equation for y, people usually write it in a simpler way. You can see this from the other answers. WebFeb 2, 2024 · Now that we know what the radius of a circle is (marked with green), let's get familiar with the rest of the lines. Circumference (blue) is the perimeter length of the circle.; The diameter (red) is a line with both endpoints on the circle going through the center.; Chord (purple) is any line with both endpoints on the circle.; In some sense, the radius is …
