PAL Worksheet 22 1. Use the given arc length and given radius to find the measure of the central angle θ (in radians). a. 25 cm θ 10 cm b. 10π 3 in. θ 8 in. π 2. In a circle with radius 1 foot, the area of the shaded sector is square feet. What is the measure 5 of the central angle of this sector? 1 ft 3. Draw a right labeling the lengths of the sides, if one of the acute angles in the triangle √ triangle, 7 −1 is θ = tan 4 . (Also label the angle θ in your picture.) 4. Draw a right triangle, labeling the lengths of the sides, if one of the acute angles in the triangle is θ = sin−1 (v). (Also label the angle θ in your picture.) Use the triangle to find cos θ and tan θ. 5. For the graph shown a. state a rule of the form f (x) = a cos(bx − c) whose graph appears to be identical to the given graph, and b. state a rule of the form f (x) = a sin(bx − c) whose graph appears to be identical to the given graph. 3 2 1 -1 -2 -3 Π Π 3Π 4 2 4 Π
