Fill in the blanks a radians b 180 degree radians Conver

Fill in the blanks: (a) = ___ radians (b) 180 degree = ___ radians Convert the following degree measures to radians. First, give an exact result. Then round each answer to the nearest hundredth. (a) 30 degree (b) 90 degree (c) 135 degree (a) 45 degree (b) 60 degree (c) 150 degree (a) 120 degree (b) 225 degree (c) 330 degree (a) 210 degree (b) 270 degree (c) 315 degree (a) 19 degree (b) 40 degree (c) 72 degree (a) 10 degree (b) 53 degree (c) 88 degree Convert the following radian measures to degrees. (a) pi/4 (b) 4 pi/3 (c) 5 pi/6 (a) pi/2 (b) 7 pi/6 (c) 5 pi/4 pi (b) 11 pi/12 (c) 61 pi/36 pi/9 (b) 7 pi/18 (c) 53 pi/30

Solution

12. a. 210 * (pi)/180 = 3.6651 , approximated as 3.7 rad

b. 270*(pi)/180 = 4.7123 , approximated as 4.8 rad

c. 315*(pi)/180 = 5.4977 , approximated as 5.5 rad

pi = 22/7
