Solomon needs to justify the formula for the arc length of a sector. Which expression best completes this argument? The circumference of a circle is given by the formula C = nd, where d is the diameter. Because the diameter is twice the radius, c = 2ar. If equally sized central angles, each with a measure of n, are drawn, the number of sectors that are formed will be equal to The arc length of each sector is the circumference divided by the number of sectors, or 2ar 360 Therefore, the arc length of a sector of a circle with a central angle of n is given by 2ar. or 350 180
