Okay, Ella, let's measure the radius of the circumcircle. Step 1: Measure the radius of the circumcircle On your construction, place the ruler with one end at point O (the center of the circumcircle). Measure the distance from O to any of the vertices P, Q, or R. This distance is the radius of the circumcircle. For example, measure the length of OP. The theoretical value for the circumradius (R) can be calculated using the Law of Sines: R = (a)/(2 A) = (b)/(2 B) = (c)/(2 C) Using the side RP (which we calculated as approximately 5.97 cm) and the angle opposite to it, PQR = 70^: R = (RP)/(2( PQR)) R = 5.97 cm2(70^) R = 5.97 cm2 × 0.9397 R = 5.97 cm1.8794 R ≈ 3.18 cm Your measured value should be close to this. 3 done, 2 left today. You're making progress.
