WebI know that only having two points is not enough for determining the circle, but given that the center is on the same x coordinate as one of the points, is there a way to use those two points to find the center/radius of the circle? What does this means in this context? In this case, r r is the distance between (2,7) ( 2, 7) and (3,8) ( - 3, 8). WebThe radius is any line segment from the center of the circle to any point on its circumference. So, we know the angle $\alpha$ of the arc between the two points -- it's just $\alpha = s/r = 2\pi/x$. In the past, ancient geometers dedicated a significant amount of time in an effort to "square the circle." We know that the arclength $s$ between the two points is given by $s = 2\pi r/x$, where $x$ is known. For example, if the diameter is 4 cm, the radius equals 4 cm 2 = 2 cm.
