Equation for circumference of a semicircle
WebMar 19, 2024 · Question 7: What is the circumference of a semi-circle? Answer: The formula for the circumference of a semicircle is C = (πr + 2r), where r is the radius. We know that diameter is twice the value of the radius, d = 2r. The formula for the circumference of a semicircle becomes C = π(d/2) + d. WebAnswer (1 of 5): Circumference of a semicircle=r(2+π). [where r=radius of semicircle.] = 12.(2+22/7) cm. = 12 ×36/7. cm. = 432/7 cm. = 61.71 cm. Answer.
