Web2. Perimeter. (π+2)r. In mathematics (and more specifically geometry ), a semicircle is a one-dimensional locus of points that forms half of a circle. It is a circular arc that measures 180° (equivalently, π radians, or a half-turn ). It has only one line of symmetry ( reflection symmetry ). In non-technical usage, the term "semicircle" is ... WebMay 30, 2024 · To 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!
