Perimeter of a semi circle is

WebSemicircle is exactly half the entire circle. Area of Semi circle = (1/2)πr2 square units. Perimeter of Semi circle = (π + 2)r units. Example 1 : Find the area of the semicircle whose radius is 7 cm. Solution : Area of Semicircle = (1/2)πr2. Substitute 7 for r and 22/7 for π. = (1/2) x (22/7) x 72. WebFeb 26, 2024 · As a semi circle is half that of a circle, so its perimeter is half the circumference of a circle along with the diameter of a circle. So, the perimeter of a semi circle becomes = 2 π r 2 + d. Where, r is the radius of the circle and d is the diameter of the circle. Also, it can be written as π d 2 + d, where d is the diameter.
