Question

  Find the length s of the arc of a circle of radius 48 centimeters subtended by the central angle one eighth radian
1/8 radian.

Answer 1

taking the problem the way it is stated...

∏ radians=180º

1 radian=180º/∏

1 radian=57.2958º

(1/8) radian=57.2958/8

(1/8) radian=7.1619º

C=2∏r

C=2∏48

C=96∏ cm

the length of the arc is(7.1619/360)(96∏)

(7.1619/360)=0.019894

arc length=0.019894*96∏

arc length=1.90982∏

arc length=1.90928*3.14159

arc length=5.99988 cm
