WebAnother formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius by 2 and times it by pie and then you get the circumference. Here are the two different formulas for finding the circumference: C = πd. C = 2πr. WebCenter of Circle Examples. Example 1: Find the equation of the center of a circle if the coordinates of the center are (0, 0) and the radius of the circle is 5 units. Solution: The center of the circle equation is (x - h) 2 + (y - k) 2 = r 2. The given values are: coordinates of the center (h, k) are (0, 0), and the radius (r) = 5 units.
