About this resource
Description
The circumference of a circle is the distance all the way around its edge, and this Circumference of Circles Worksheet gives students focused practice finding it. Working with circles helps learners connect a circle’s radius and diameter to the special number pi (π ≈ 3.14). Once students can measure across a circle, this circumference of circles worksheet shows them how to turn that measurement into the distance around the whole shape.
This 6th grade circumference worksheet presents six clearly drawn circles, each labeled with either its diameter or its radius. Students apply the formula C = π × d, remembering that the diameter is twice the radius, and round each answer to the nearest hundredth. A handy reminder box at the top keeps the formula in front of them, so they can work independently at their desks, in a math center, or as homework.
What’s Included
- 1 print-ready PDF worksheet
- Answer key
- 6 circle problems using radius and diameter
There are three reasons this circumference of circles worksheet helps students master the skill. First, mixing radius and diameter problems pushes learners to think about the relationship between the two instead of memorizing a single procedure. Second, rounding to the nearest hundredth builds real number sense with pi and decimals. Third, the clean, labeled figures let students focus on the math rather than decoding a busy page, which builds confidence with every problem they solve.
Teachers and parents can extend the learning in fun, hands-on ways. Have students measure round objects around the room — cups, cans, clocks, and bicycle wheels — with a piece of string, then compare their measurement to the calculated circumference. Challenge students to work backward from a known circumference to find the diameter, or to estimate before they calculate. Connecting circumference to everyday circles makes the concept stick long after the worksheet is finished.
