A circle has a circumference of 6. If has an arc of length 1/3. What is the central angle of the arc, in degrees? HELP ME PLIS 🥺

Answer 1

2*pi*r = 6. So you know radius from this. Arc length = radius * angle (in radians). [This is actually the famous formula for circumference as well - arc length is circumference for a full circle, which is equal to radius * (2*pi).] From this you know angle but in radians. Convert radians to degrees.
