Find the exact value without using a calculator Electrical w
Find the exact value without using a calculator. Electrical wire is being woand aroand a drum with radius of 0.95 motors How much line (to the nearest handredth of a meter) would be woand aroand the drum if it is rotated through an angle of 340.tF? Find the value of s in the interval (0, n/21 that makes the statement true. Roand to four decimal places. Convert the radian measure to degrees. Give answer using decimal degrees to the neatest handredth. Use 3.1416 torn. Find the exact value without using a calculator.
Solution
29)cos2pi =cos0 =1
30)L=pi*r(/180) given in degrees
given =340.8o,r =0.95
L=pi*0.95(340.8/180)
L=5.65m
5.65 m line would ne wound around the drum if it is rotated through angle of 340.80
31)tans=2.8438
s=tan-12.8438
s=1.227 radians
32) 5 radians
=5*(180/pi)
=286.480
33)sin(5pi/3)
=sin(2pi -pi/3)
=-sin(pi/3)
=-(3)/2
