Draw yourself a picture of the fence - 100 feet long.
Draw the dog at 50 foot mark.
The leash is 20 feet long. Mark a point at 30 feet of the fence and at 70 feet along the fence. ( This is the extent of the leash)
Then join those two marks (30 and 70) with half circle. This is the area the dog can reach. (The circumference of the half circle is the 20 feet of the leash.)
Your job: to do the math with pie (2.14) and all that. I gave you the picture. . .

perhaps after a time but he has plenty of room to run around so the grass may take some time to wear away
