A Dog Problem

Geometry Level 3

A dog is chained to a point of the side of a circular lighthouse of radius 1. The length of the dog’s chain is pi. The dog may not go inside the lighthouse. How much area can the dog cover?

I took this problem from: http://mathproblems.info/

7 π 2 {7\pi}^{2} 6 π 2 7 \frac { { 6\pi }^{ 2 } }{ 7 } 3 π 3 { 3\pi }^{ 3 } 5 π 3 6 \frac { { 5\pi }^{ 3 } }{ 6 }
