Area and Circumference of Circles
Below you’ll find a variety of printable “Area and Circumference of Circles Worksheets!”
Circumference is just a fancy word for perimeter, which is the distance around the circle (written in units). Area is the space inside (written in square units).
The formula for circumference is C = 2πr, where r is the radius. The formula for the area of a circle is A = πr². Since area is always written in square units, you can easily remember that the formula for the area of a circle is the one with the “squared” in it.

Area of a Circle (Printable PDFs)
In these worksheets, students will practice calculating the space inside. The formula for the area of a circle is A=π r², where r is the radius (the distance from the center to a point on the circle). For circles with the diameter labeled, cut it in half to find the radius. Label answers in square units. All worksheets include answer keys.
