Circumference
The circumference of a circle is the distance around the edge of the circle. It is similar to the perimeter of other shapes, such as rectangles or squares, but specifically refers to the distance around a circle.
Formula for Circumference
The formula for finding the circumference of a circle is:
C = 2πr
where C is the circumference, π (pi) is a constant approximately equal to 3.14159, and r is the radius of the circle.
Study Guide
- Understand the concept: Make sure you understand that the circumference is the distance around the circle, and how it is different from the area of the circle.
- Learn the formula: Memorize the formula C = 2πr, and understand what each symbol represents.
- Practice with examples: Work through practice problems to calculate the circumference of circles with different radii.
- Use π (pi): Understand the significance of π and how it is used in the formula to find the circumference.
- Real-life applications: Look for real-life examples where understanding the circumference of a circle is important, such as in engineering or design.
By understanding the concept of circumference and practicing with the formula, you can become proficient in calculating the distance around a circle.

The Number System
Apply and extend previous understandings of numbers to the system of rational numbers.
Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates. [6-NS6]
Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes. [6-NS6b]
Find and position integers and other rational numbers on a horizontal or vertical number line diagram; find and position pairs of integers and other rational numbers on a coordinate plane. [6-NS6c]
Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate. [6-NS8]
