Circumference and arc length
Web4 rows · If the angle subtended by an arc is θ°, then it means that the arc occupies a fraction of θ/360 ... WebCircumference= 2pi*r which is also equal to diameter*pi. Therefore the circumference of the circle is 16pi. The arc measure is equal to the central angle that intercepts it. Since line CA is a diameter, it is equal to 180 degrees, so if you add the measures of angles DPA and DPC, it will equal 180 degrees.
