WebCross Sectional inside Pipe Area. Cross-sectional inside area of a pipe can be calculated as. A i = π (d i / 2) 2 = π d i 2 / 4 (1) where. A i = cross-sectional inside area of pipe (m 2, in 2). d i = inside diameter (m, in). … 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.
WebMar 29, 2024 · The formula tells you that the circumference is the diameter multiplied by pi, so that means whatever diameter is given needs to be multiplied by 3.14 to find the circumference.
