WebHow to compute the area of circle from diameter? We all know the famous area of circle formula: A = \pi r^2 A = πr2. The only "problem" is that this circle formula requires the radius. But notoriously, the radius (r) and diameter (d) are related through the formula r = \frac {d} {2} r = 2d. WebFeb 17, 2016 · A. In order to calculate a circle’s circumference, we need to know either its diameter or its radius. We then use the appropriate value in this equation: C = 2 π r (where “ r ” represents radius, of course). Ex. Find the circumference of this circle: r = 10 units 2 = 5 units. C = 2 π r = 2 π × 5 = 10 π units. Q.
