We are looking for a distance, and so we need to calculate the circumference first. The circumference is the distance around the circle.

Circumference formula:

C=2r

Input radius value:

C=2(5)

Simplify:

C=31.414

So, the circle is 31.414mm in length.

Now, we need to find a fraction of this length. Remember, an arc is a fraction of the circle. We know a circle is 360° and the given arc is 232.° So, we can are looking for 232/360 of the circle’s circumference.

Arc length=232/360•31.414

Arc length=20.244

The billed arc length is about 20.244mm.

All we did was take a fraction of the circumference. The fraction was found because we are given 232 degrees out of 360, and degrees form arcs.
