WebAdding the diameter of the circle to the equation gives us the equations for the perimeter of a semicircle: or P = πr + 2r where P is the perimeter, d is the diameter, and r is the radius of the semicircle. Area of a semicircle WebA semicircle is half of a circle. The "measure" associated with an arc A circle is associated with a complete rotation, which is 360°. A semi-circle is associated with half of a rotation which is 180°. Minor arcs are associated with less than half of a rotation, so minor arcs are associated with angles less than 180°.
