10 problems to practice finding the area of an annulus (donut). Great practice to master finding area of a circle and understanding composite area.
The first 8 problems have work space for students to show the area of the larger circle, the area of the smaller circle, and the difference. The last 2 problems have space for work, but students need to show their own steps.
