Unit 3 test

Unit 3 Circles Test Directions: Please complete the following problems to the best of your ability. Always show your work. Even if it means writing down your thought process, I must know how you came up with your solution. Problems with little to no work shown will result in little to no credit. 1. What is the length of LN in the circle shown below? This figure shows circle 0 with chords PM and LTV. mPL = 10 ' /_'\\ le'i/I : 14\" m/LN\\ : 24': PILI : 15111. 2. The circle shown in the picture below has a diameter of QS. The measure of the arc RSQ is 290 degrees. What is m A C AC is tangent to the circle with center / r' at B. The measure of AACB is 71". f d/ | B What is the measure of LABC? K / 5. In the image below, chord AC intersects chord BD at point P in circle Z. AP =12m DP = 5m PC = 6m What is the length of BP? 7. A circle has a radius of 12.6 cm. What is the exact length of an are formed by a central angle measuring 120 degrees? 8. A circle has a radius of 8ft. What is the area of the sector formed by a central angle measuring 3pi/ 4 radians? (That's 3pi over 4 as in a fraction.)
