Arc Length Conjecture
What is the CIRCUMFERENCE of the given circle (r = 4 cm) in terms of pi?
[math]4\pi[/math] centimeters
[math]16\pi[/math] centimeters
[math]8\pi[/math] centimeters
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 [b]length of an arc[/b] of a circle is simply a ______________ of the full circle's circumference.
remainder
fraction
divisor
To determine the fraction that should be used in our calculations, we must know the size of the angle located at the circle's center.
