    Re: Finding the Diameter

    Since the arc is 60 degrees, the area of the sector is 1/6 of the area of the whole circle.

    Re: Finding the Diameter

    Because the sector area is 24pi, the area of the entire circle is 24pi*6=144pi. This means the radius is 12, and so the diameter is 12*2=24
