4. Next, using the line equations found in the previous step, we solved using the //system of equations.// The intersection coordinates are (2.056, -0.056).
5. And finally, we used the distance formula to find the distance from the cicumcenter to each vertex. This verified the circumcenter's coordinates and gave us a near exact measurement for the radius. //Please note:// In the calculations, we rounded minimally-- because of this the distances may be off by a few hundredths or so. Then, to make the radius as exact as possible, we added all the distances together and divided by three (found the average, which is 4.068cm).

6. //Ta-Daaa!// Here is our final product of //lots// of calculations. The circumcenter is plotted, with a circle drawn to demonstrate that it intersects each vertex.
