Think of the rope as the radius of the circle. But he can only get 3/4 of the circle because the shed corner takes up a quarter of the circles area. So use (pi)(r)(r) to find the area of the circle then multiply by 0.75 and you have the grazing distance the goat can go (assuming he does not eat his way through the rope... and go to the next farmers field : )
how big is the shed?
