Farmer's Fred's lawn mower is broken, so he put his goat in his front yard on a stake that pivots 360°. The length of the rope from the stake to the goat's collar is 8 feet.

If the stake is the center of the circular area of yard available for the goat to eat grass, what is the area of the yard available for the goat to eat grass, to the nearest whole square foot?
