First, we need to calculate the circumference of the air duct first according to the formula:
C= D x 3.14
After calculating the circumference, we will calculate the area of the circular duct according to the formula:
S= C x L
Above is the most accurate formula for calculating the perimeter and area of the air duct that you can refer to and apply to your work.
