So are we to assume that the cow can go around the 2ft wall and continue eating grass?  So effectively, the rope is 6 feet at that point?

anonymous · Answer

cow is very smart and green area is all grass..

mr.math · Answer

So we have 20 ft of fences?

mr.math · Answer

If so, then the maximum area needed is that of a circle with perimeter of 20 ft, that's radius of $\large \frac{10}{\pi}$ and area $\large \frac{100}{\pi} \text{ft}^2$.

barrycarter · Answer

It looks like the cow can eat a half-circle of grass with radius 8ft, 
and then another half-circle of grass with radius 6ft. That's: 
 
1/2*Pi*8*8 + 1/2*Pi*6*6 = 50 Pi =~ 157.08 square feet of grass

barrycarter · Answer

Correction: the 6ft rope should centered at the west edge of the fence, not where the cow is.
