5 dni temu · Formula to calculate the diameter of a circle given its radius, or vice versa. The formula of the diameter of a circle is the most straightforward of the equations and says that diameter ( d) equals twice the radius ( r): d = 2r. r = d/2. The calculation of circumference and area of a circle formulas are more tricky.
