WebFree Circle equation calculator - Calculate circle's equation using center, radius and diameter step-by-step
WebExplanation: . The general equation of a circle is (x – h) 2 + (y – k) 2 = r 2, where (h, k) represents the location of the circle's center, and r represents the length of its radius. Circle A first has the equation of (x – 4) 2 + (y + 3) 2 = 29. This means that its center must be located at (4, –3), and its radius is √29. WebThe equation for diameter of a circle from circumference is: d=c/\pi d = c/π. If written instead in terms of the radius, the diameter is very simple; it's just twice as long: d = 2r d = 2r.
