Circumference of semicircle f
WebThe perimeter of the semicircle = πr + 2r. = (π × 12) + (2 × 12) = 37.68 + 24. = 61.68 units. Therefore, the perimeter of the semi-circle is 61.68 units. You can verify the result with the circumference of semicircle calculator given on this page. Similarly, you can try the calculator to find the perimeter of the semi-circle using the ... WebTo calculate the length (= the arc length) you need to calculate the whole circumference first and then multiply it by 3/4 to find the length you really want: Whole circumference = 2*Pi*radius = 8*Pi = approx. 25.13dm, The length that you need: (8*Pi) * (3/4 ) = 6*Pi = approx. 18.85dm. Hope that helps!
