+99 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)
+9466 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
+99 I had 175.93 and I was sure that was right. but it was not LOL Your answer was correct. Thanks!
