In circle O, m∠POQ=40∘ and the length of PQ=23π. Find the length of OP―.
3.0
Step 1 :Convert the given angle from degrees to radians: angleinradians=angleindegrees∗π180
Step 2 :angleinradians=40∗π180=0.6981317007977318
Step 3 :Use the rearranged arc length formula to find the length of the radius OP: radius=arclengthangleinradians
Step 4 :radius=23π0.6981317007977318=3.0
Step 5 :3.0
