Question 2799
Since the goat is tied to the corner of the square barn....goat will be able to graze a Three quarters of the circle with radius 28 ft outside the barn.

so square feet of land grazed will be 3/4(pi*r*r) = 3/4(22/7)(28*28)
=> 616*3 sq ft=1848 sq ft. Please modify your solution. Gbeach
