Webb12 apr. 2024 · The perimeter of a circle is given by $ 2\pi r$. But since the semicircle is half the circle, we get the perimeter of a semicircle as $ \pi r$. But for a semicircle, you have an additional line of length 2r at the bottom of a semicircle. Therefore, the perimeter of a semicircle is $ \pi r+2r$. Here, substitute r = 4 ft to get the final answer. WebbDescription for Correct answer: The perimeter of a semi-circle = π r + 2 r. where r is the radius of the circle. π r + 2 r = 36. r ( π + 2) = 36. r = 36 π + 2 = 36 22 7 + 2 = 36 × 7 36 = 7cm. Therefore, Diameter of the semi-circle = 2 × 7 = 14 cm. Part of solved Area and perimeter questions and answers : >> Elementary Mathematics >> Area ...
