Using the perimeter of a semicircle formula, Perimeter of a semicircle = πr + d = πr + 2r. = (7 × 22/7 + 14) units. = (22 + 14) units. Answer: The perimeter of the semicircle is 36 units. Example 3: Using the semicircle formulas, calculate the circumference of a semi-circle whose diameter is 8 units. WebSep 29, 2024 · There are two formulas that can be used to calculate the circumference of a circle: C = 2πr or C = πd, where π is the mathematical constant approximately equal to 3.14, [4] r is equal to the radius, and d is equal to the diameter. [5] Because the radius of a circle is equal to twice its diameter, these equations are essentially the same. sick optex wt260-r280
