DIRECTIONS: Read the question and select the best response.
The radius of the largest circle is 8 inches. Find the area of the shaded region.
There are two circles, both centered on point O. One circle is larger than the other. Both circles are bisected by a line that goes upwards from left to right. The length of the segment of the diameter line between the exterior circle and the interior circle is marked as being the same as the length of the segment from the interior circle to point O. There is also a ray extending from point O downwards left to right to the exterior circle. The angle between the ray and the diameter line that is pointing downwards is marked as sixty degrees. On the other side of the ray extending to the diameter line, the area between the interior and exterior circle is shaded.
