In a circle center, O, AOB, and COD are two concentric sectors. The lengths of the arcs AB and DC are 2.8 cm and 2 cm respectively, and AD= 2cm. What is the length of OC? I don't know how to find any of the other variables to plug into my formulas and I'm stuck.
+37093 Hmmmm.... is the smaller sector CENTERED within the larger ? Maybe? I think I can solve it if it is centered..... DO you have a diagram?
