Question

Determine the arc length of a circle that has a 7-centimeter radius and a central angle that is 40 degrees. Use 3.14 for π and round your answer to the nearest hundredth.

Answer 1

Given:
Radius = 7cm
Central angle (theta) = 40 degrees

Asked:
Arc length (s)

SOLUTION:
s = 2*pi*radius*(central angle/360)
s = 2(3.14)(7cm)(40 degrees/360 degrees)
s = 4.88 cm

Therefore, the arc length of the circle is 4.88 centimeters.
