To calculate the area of an equilateral triangle, you only need to know the side: area = a² × √3 / 4. Since √3 / 4 is approximately 0.433, we can formulate a quick recipe: to approximate the area of an equilateral triangle, square the side's length and then multiply by 0.433.Step 6. Measure the length of the duct in feet (if you want to translate the two-dimensional area to the three-dimensional volume), then multiply the area by the length. Continuing this example, for a 10 foot duct the area is 23.9 feet. Advertisement. Duct areas in square feet can be calculated by using geometry rules for round areas.To find the radius from the diameter, you only have to divide by two: r=d/2 r = d/2. If you know the circumference it is a bit harder, but not too bad: r=c/2\pi r = c/2π. Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia) Area, on the other hand, is all the space contained inside the circle.Free online area of a circle calculator which helps you calculate the are of any circle, given its radius.
