Circumference of a semi circle
WebPerimeter of a semicircle is the sum of the half of the circumference of circle and its diameter. As we know that, perimeter of circle is 2πr or πd. So, perimeter of a semicircle is 1/2 (πd) +d or πr +2r. Formula is. Perimeter of a Semicircle = d (1/2 π + 1) or r (π + 1) Where, r is the radius and d is the diameter. 2.
