WebThe perimeter of a semicircle is the sum of half of the circumference of the circle and its diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius. … WebThe circumference of a circle is the length of the curve that encloses that circle. A circle is defined by only two things: its center and its radius. Two circles with the same center and the same radius are the same circle. Therefore, the circumference of a circle must depend on one of these, or both. In fact, the circumference is dependent ...
