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.

WebPerimeter of semicircle =36cm πr+d=36 ⇒πr+2r=36 ⇒r( 722+2)=36 ⇒ 736×r=36 ⇒r=7 ∴ Diameter 2r=2×7=14cm Was this answer helpful? 0 0 Similar questions In the given figure, O is the centre of the circle AB and CD are diameters perpendicular to each other. Find the ratio of the perimeter of the semi-circle ADB and triangle ADB Hard View solution > WebHence, Perimeter = πr +2r. Area of Semi-Circle. Area of the semi-circle is the region occupied by a semi-circle in a 2D plane. The area of the semi-circle is equal to half of the area of a circle, whose radii are equal. Therefore, Area = πr 2 /2.
