Question

In circle O, central angle COD has a measure of 48°. Find the measure of arc BC. In your final answer, include all of your work.

Answer 1

This is the concept of geometry;
to get the length of arc BC we shall proceed as follows;
angle DOC=48°
angle BOC=180-48=132°
curcumfrence of a circle is given by:

π×diameter×(theta)/360

The length of arc BC will be given by:
length,circumference=π×d×132/360
=11/30πd units
=1.152d units
where d is the diameter of the circle
