Question
5. Find the area, to the nearest square unit, of the sector of a circle with the given radius and central angle for each problem below. Show your work. A = r²0 2πT C. r = 2.8 ft 0 = C. 5 D. r = 20 m 0 = 220° D. 6. True or False? (Write out the COMPLETE word that you choose for each answer.) A. TT The length of an arc with central angle in a unit circle is 4. 4 A. B. If the radius of a circle doubles, then the arc length (associated with a fixed central angle) doubles. B. C. For a circle with radius r = 2.2 cm and a central angle measuring 25°, the area of the circular sector is 60.5 cm². C.
