• 1. 1. Identify the facts about (Pi)2. What is the circumference of a circle whose diameter measures 12cm? 24 cm? 16 cm? 33cm?3. A circle has a circumference of 80 m. What is the measure of the radius of thegiven circle?4. What is the area of a circle whose diameter measures 18cm?5. A circle has an area of 625 m2. What is the measure of the diameter of thegiven circle?For numbers 6-8, refer to the figure below: 26. If the measure of arc AB is 24o and arc CD is 56 degrees, what is the measure of 2 ?7. If m1 = 88 and arc CD measures 70o what is the measure of arc AB and the sum of the measures of arcs AD and BC respectively?8. If arc CD measures 7b 12, arc AB measures, 20b 8, m1 = 5b + 4 , what is the measure of angle 1 and 2?True or false:1) The measure of an inscribed angle is half the measure of its intercepted arc.2) If an inscribed angle intercepts a semi-circle, then the inscribed angle is right.3) If two inscribed angles intercept the same or congruent arcs, they are also congruent.4) If a quadrilateral is inscribed in a circle, then the consecutive angles are supplementary.5) The measure of a minor arc is half the measure of its central angle.6) The measure of a minor arc is equal to the measure of its central angle.7) The measure of a minor arc is twice the measure of its central angle.8) The measure of a minor arc is 360 minus the measure of its central angle.
