How to Calculate the Circumference of a Circle The radius is half as long as the diameter, so the diameter can be thought of as 2r. Keeping this in mind, you can write down the formula for finding the circumference of a circle given the radius: C = 2πr. In this formula, r represents the radius of the circle.

If the diameter of a circle is 5 feet, what is the circumference? The Circumference of a Circle is defined by the formula: C = 2πr where r is the radius of a circle. The diameter of a circle is twice its radius or 2r and therefore C = πd (where d is the diameter). So since d = 5 feet, the Circumference of the c...

Perimeter The perimeter of a circle, often called the circumference, is proportional to its diameter and its radius. That is to say, there exists a constant number pi, π (the Greek p for perimeter), such that if P is the circle's perimeter and D its diameter then: In terms of the radius r of the circle, this formula becomes:

USCG Navigation General Questions: Master's License The radius of a circle is any line segment from the center of the circle to any point on the circle. The diameter of a circle is any line segment that passes through the center of the circle and has its endpoints on the circle. In any circle, the length of a diameter is twice the length of a radius. Radius and diameter are also used to name length. For example, the radius of the circle is 2 inches and the diameter is 4 inches.

Calculating the circumference of a circle The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference (c). A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d) Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r).

The Geometry of Circles The radius of a circle is the distance from the center of the circle to the outside edge. The diameter of a circle: The diameter of a circle is longest distance across a circle. (The diameter cuts through the center of the circle. This is what makes it the longest distance.) The circumference of a circle (the perimeter of a circle): The circumference of a circle is the perimeter -- the distance around the outer edge. Circumference =. where r = the radius of the circle.
