Equation for the diameter of a circle
Webdiameter = 2 × radius. We can actually rewrite the circumference equation using radius instead of diameter: c = πd = π(2r) Mathematicians usually write it like this: c = 2πr. The formula for circumference of a circle is 2πr. Let's use this formula to find the circumference of the circle below. c = 2πr. WebThe radius is any line segment from the center of the circle to any point on its circumference. In this case, r r is the distance between (1,6) ( 1, 6) and (−2,4) ( - 2, 4). Tap for more steps... r = √13 r = 13 (x−h)2 +(y−k)2 = r2 ( x - h) 2 + ( y - k) 2 = r 2 is the equation form for a circle with r r radius and (h,k) ( h, k) as the center point.
