These worksheets teach your students how to calculate the circumference and perimeter of different figures.

#### If you were run all the way around a circle the distance that you would travel is called the circumference. Any straight line that travels through the center of a circle and touches end to end of a circle is called the diameter. You might have heard of the famous symbol pi ( π )? π is used to define the ratio of the circumference of circle to its diameter. This just means that if you know the circumference and dimeter of a circle, you can divide the circumference by the diameter, and you will get a value that is pretty close to 3.14. Using π and understanding the relationship of this ratio we can tell a great deal about the measures of a circle include circumference, diameter, and radius. Using the form of math is how traffic circles are created and it is also how farmers tell how much grain their silo will hold for all the animals.

In this series of printable worksheets you will look to calculate the distance around a circle. You will use the standard formula two-pi-radius. We also introduce perimeter in this section. Try not to confuse the two measures. Circumference is very similar to perimeter because it is a measure of the length around a two-dimensional figure. The main difference is that circumference looks for distance across curved or arched segments. These worksheets explains how to find the circumference of a circle and the perimeter of any shape. Your students will use these sheets to learn how to calculate the circumference and perimeter of different figures (circles, squares, etc.).

## Circumference Lesson

This worksheet explains how to find the circumference of a circle. A sample problem is solved.

## Lesson and Practice

You will calculate the value of each circle when you are given either a diameter or radius.

## Worksheet

Writing the lengths of radius and diameter on the worksheet is a good habit to get into.

## Topic Drill

I would add extra credit by having students name what each line indicates.

## Warm Up

If you have not broken down the anatomy of a circle and lines that pass through it, now is a good time to do so.

## Find the Circumference Lesson

Using the formula Circumference = 2π × radius.

## Class Worksheet

Students will find the distance around a circle when given the radius or the diameter. Ten problems are provided.

## More Practice

By now this skill should be pretty quick for you.

## Quiz

Students will demonstrate their proficiency with this skill.

## Topic Check

Three problems are provided, and space is included for students to copy the correct answer when given.

## Perimeter Lesson

This gives you a quick refresher on finding perimeter.

## Perimeter and Circumference Worksheet

We put both skills to work for us and we start to understand the differences.

## Review

You will need to mix your skills to handle this one well.

## My Practice

See how you work well in this scheme of things.

## Skill Quiz

You will need to determine what each measure means and not get distracted by non-issues for the problem.

## Check

A nice way to track you through this skill.
