Circumference and Arc Length Answers
Minor arc KL measures 135°.
In circle M, diameters JL and HK each measure 16 centimeters.
In circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°.
Two similar circles are shown. The circumference of the larger circle, with radius OB, is 3 times the circumference of the smaller circle, with radius OA.
Circle O has a circumference of approximately 250π ft.
Major arc CBD measures 300°.
Two circles are shown in the diagram.Since all circles are similar, a proportion can be set up using the circumference and diameter of each circle. Substitute the values d1 = 1, C1 = π, and d2 = 2r into the proportion.Which shows how to correctly solve for C2, the circumference of any circle with radius r?
