What is the length of the arc on a circle with radius 10 cm intercepted by a 20° angle?
Use 3.14 for π .
Round the answer to the hundredths place.
+36916 The entire circle circumference is given by 2piR = 2 pi (10) = 20 pi cm
20 degrees' worth out of 360 is given by
20/360 x 20 pi = 400 pi /360 = 400(3.14)/360 = ~3.49 cm
