This second formula for finding the circumference of a circle is commonly used in problems where the diameter is given and the circumference is not known (see the examples below).
Formula For Circle Diameter. 1 calculating the diameter of a circle using the radius, circumference, or area. Its center (or middle) and its radius (the distance from the center to any point on the circle).

To calculate diameter from the area, divide area by pi value (pi = 22/7 or 3.14). In this we discuss about properties of circle, circle formulas like area, perimeter, arc length, segment diameter: Its center (or middle) and its radius (the distance from the center to any point on the circle).
Yet, with just the diameter, or half the diameter (the radius), or even only the circumference (the distance around), you can calculate the area of any circle.
Learn to find the diameter or radius of a circle given the circumference. If you know the diameter or radius of a circle, you can work out the circumference. Yet, with just the diameter, or half the diameter (the radius), or even only the circumference (the distance around), you can calculate the area of any circle. Because people have studied circles for thousands of years special names have come about.
