Question 10
The diagram shows a sheep on a lawn, tied by a string to a metal rod parallel to the ground. The length of the string is 10 m, and the length of the metal rod is 3 m. The sheep is of negligible size and the height of the rod above the ground is also negligible. Taking $\pi\approx3.14$, what is the area, in m², of the part of the lawn from which the sheep can eat the grass?
