Area of an Annulus Worksheets

Casting around for free worksheets to practice finding the area of an annulus? You've hit the jackpot with our pdf worksheets! Get used to the fact that an annular region is formed between a pair of concentric circles, and find its area. How would you calculate the area of such circular rings? It's super-simple. Just subtract the area of the inner circle from the area of the outer circle to find the area enclosed in between. Writing that down as a formula, we have: A = πR2 − πr2, where R is the radius of the outer circle and r is the radius of the inner circle. Solve the three levels by determining the area of an annulus in terms of pi as well as plugging in π ≈ 3.14.

We suggest our worksheets on the area between two concentric circles for grade 8 and high school students.
