Arc Length Conjecture
What is the CIRCUMFERENCE of the given circle (r = 4 cm) in terms of pi?
Rounded to the nearest hundredth of a centimeter, the circle's FULL circumference is 25.14 centimeters.
Since we can calculate the FULL circumference of any circle, we can easily compute arc length too.
The length of an arc of a circle is simply a ______________ of the full circle's circumference.
