Question

Determine the length of an arc with the given central angle measure, m<w=20;r=1 and round the answer to the nearest hundredth.

Answer 1

recall that length of arc is given by
s = r*theta
where
r = radius
theta = angle in radians
first we convert the given angle to radians:
20 * pi/180 = pi/9 = 0.349 rad
substituting,
s = 1*0.349
s = 0.349
s = 0.35 (nearest hundredth)

hope this helps~ :)
