Circle Worksheets

This generator makes worksheets for calculating the radius, diameter, circumference, or area of a circle, when one of those is given (either radius, diameter, circumference, or area is given). You can choose to have metric or customary units, or both. You can choose to include simple circle images in the problem, or not, or randomly have some problems have circle images and some not. You can also make the script use either 3.14 or 3.1416 as a value of Pi in the calculations, and to choose the rounding accuracy for the answers. Please change the different options to see what their effect is.

After you have generated a worksheet, you can just refresh the page from your browser window (or hit F5) to get another worksheet with different problems but using the same options.

All worksheets come with an answer key.  You can print the worksheet directly from your browser, or save it on disk using the "Save as" command of your browser.  If the problems on the worksheet don't fit the page or there is not enough working space, choose a smaller font, less cellpadding, or fewer columns of problems.

Some quick links:

Radius/diameter practice: calculate radius when diameter is given or vice versa

Find the circumference when either radius or diameter is given

Find the area of the circle when either radius or diameter is given

Find the area or the circumference when either radius or diameter is given

Mixed practice of all the "basics": either radius or diameter is given, calculate area/circumference/radius/diameter

Calculate diameter/radius/area when circumference is given

Challenges: find the radius/diameter/circumference/area when area or circumference is given (often requires usage of square root)
