What is the length of an arc with a central angle of 4/3π radians and a radius of 42 cm?

 

Use 3.14 for pi. Round to the nearest hundredth, if necessary.

 

Enter your answer as a decimal

 

(4/3 is 4 over 3 in fraction form)

arc length = radius * central angle in radians

arc length = 42 cm * 4/3π

arc length = 56π cm

arc length ≈ 56(3.14) cm = 175.84 cm
