How to Calculate the Area & Circumference of a Circle As noted above, the circumference of a circle is the length of the line around the edge of the circle. A circle's circumference, c, is equal to twice its radius, r, times π. To calculate circumference, then, you multiply the circle's radius by 6.28. Take a circle with a radius of 4 inches.

Circumference The circumference of a circle is related to one of the most important mathematical constants. This constant, pi, is represented by the Greek letter π. The first few decimal digits of the numerical value of π are 3.141592653589793 ... (see A000796). Pi is defined as the ratio of a circle's circumference C to its diameter d: =. Or, equivalently, as the ratio of the circumference to twice the radius. The above formula can be rearranged to solve for the circumference: = ⋅ = ⋅.

How to Calculate the Circumference of a Circle In this equation, C represents the circumference of the circle, and d represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi. Plugging π into your calculator will give you its numerical value, which is a closer approximation of 3.14.

What is pi? Simple geometry â Math, circles, circumference, diameter Pi is a number that is approximately equal to 3.14. It is the number you get if you divide the circumference of any circle by its diameter. It's the same for all circles. You can approximate pi for yourself by taking some circular things like the tops of jars and CD's and frisbees and measuring their diameter and their circumference.

Fourth Grade Geometry: How to Find the Circumference Finding the Circumference in Fourth Grade. The circumference is the distance around a circle. For example, if you wanted to know the distance around a circular swimming pool, you could find it by measuring the pool's circumference. First, you'll need to know either the circle's diameter or its radius to figure out its circumference.

Perimeter Perimeter is the distance around a two dimensional shape, a measurement of the distance around something; the length of the boundary. A perimeter is a path that surrounds a two-dimensional shape. The word comes from the Greek peri (around) and meter (measure). The term may be used either for the path or its length - it can be thought of as the length of the outline of a shape. The perimeter of a circle or ellipse is called its circumference. Calculating the perimeter has considerable practical applications.

11 Methods for Teaching Reading This program is the “gold standard” for teaching reading to kids with dyslexia. It focuses at the word level by teaching the connections between letters and sounds. Orton–Gillingham also uses what’s called a multisensory approach. It taps into sight, sound, movement and touch to help kids link language to words. Students learn the rules and patterns behind why and how letters make the sounds they do. Orton–Gillingham is the basis for a number of other reading programs. These programs are mostly used by special education teachers.

- Circumference of a circle is the linear distance calculated along its edge. It is similar to perimeter of a geometric figure, but the term 'perimeter' is rather used to describe the property of polygons. Circumference is often misspelled as circumfrence.
