About this resource

Description

This Circle Circumference Worksheet gives sixth-grade students focused practice finding the distance around a circle. Circumference is the perimeter of a circle, and learners find it by multiplying pi (about 3.14) by the diameter. Working through each problem, students see how the radius and diameter of a circle connect to its circumference and build confidence with the formula C = π × d.

This 6th grade circumference worksheet presents six labeled circles followed by two real-world word problems. For each circle, students read whether the radius or the diameter is given, double the radius when needed, and multiply by pi to find the circumference. The clear diagrams and reference box make it easy to use for independent practice, math centers, homework, or a quick review before a quiz. A complete answer key is included so students and teachers can check every calculation.

What’s Included

  • 1 print-ready PDF worksheet
  • Answer key
  • 6 labeled circle problems and 2 real-world word problems

This circle circumference worksheet helps kids in three important ways. First, it reinforces the relationship between radius and diameter, so students stop confusing the two. Second, the mix of radius and diameter problems requires real thinking instead of repeating a single step. Third, the word problems show where circumference appears in everyday life, from a round pizza to a spinning bicycle wheel, making the math meaningful and memorable.

Teachers and parents can extend this skill in many hands-on ways. Hand students a piece of string and a ruler and let them measure the circumference of jar lids, cans, and plates, then compare their results to the formula. Challenge learners to find the diameter when the circumference is known by working backward. You can also connect circumference to real projects, such as measuring a bicycle wheel to predict how far it rolls in one full turn.
