Estimate the cost of the concrete requred to make a concrete sidewalk shaped as follows.

(The sidewalk covers 1/4 of the outer perimeter of a circle - from 3:00 to 6:00. The radius from the center of the circle to the outside perimeter is 20 feet. The radius to the inner circle/left side of sidewalk is 15 feet. So the width of the sidewalk is approx. 5 feet wide, covering 1/4 of circle.)

The depth of the concrete is 4 inches. The concrete costs $105/cubic yard.

thank you.
