Answer:
Explanation:
<EAF is a central angle. Its measure is 12o
Arc EF has angular measure of 12 degrees as well.
The formula for the arc length in cm is
Arc length = (given arc angle/360) * 2 * pi * r
r = 30 cm which is given
Given arc angle = 12 degrees.
Arc length = (12/360) * 2* pi * r
Arc length = 1/30 * 2*pi * 30
Arc length = 6.28
