Ac is the diameter. calculate the area of the sector (to the nearest whole number) created by ∠cdb.

any would be awesome : -)

Area of the circle is πr² which corresponds to an angle of 360° subtended at the center. Thus, the area of a sector subtending angle at the centre is:

In this case put $\theta$ equal to 30°

what exactly do you need to find in this solution like graph absolute value evaluate solve for the inequality for x???
