Therefore, a construction or doing the problem out by hand is not an option, I need to derive an equation for the center point.A sector is created by the central angle formed with two radii, and it includes the area inside the circle from that center point to the circle itself. The portion of the circle's circumference bounded by the radii, the arc, is part of the sector. Arcs of a Circle. Acute central angles will always produce minor arcs and small sectors. The distance a from the center is called the radius of the circle and the perimeter of a circle is called the circumference. In this sense, all points on the circumference of a circle are equidistant from its center.

Inputs: either coordinates for the center of the circle and a radius (in meters), or coordinates for both the center and a point somewhere on the circumference. Coordinate values need to be in decimal degrees. (The dafault values will produce a circle with a radius of 10km centered on Google HQ.) How to Find the Radius of a Circle ... For example, if your circle has a diameter of 4, the radius is 4/2 = 2. Divide the circumference by 2 pi to find the radius if you know c. it's impossible to write the exact value of pi, but for most problems 3.14 is a good enough approximation. So, if your circumference is 618, you would get r = 618 / 2 ...
