Diameter and area formula
WebThis tool will calculate the area of a circle from the diameter, and will convert different measurement units for diameter and area. Formula. The formula used to calculate circle area is: A = π x (ø/2) 2. Symbols. A = … WebFeb 20, 2024 · The general formula for the area of the circle A is A = r² × π. Since the diameter d corresponds to twice the radius r, the formula therefore is A = (d / 2)² × π. If we convert this formula to d, the diameter d is equal to twice the square root of the area of the circle A divided by Pi (π = 3.1415...), thus d = 2 × A / π.
