WebA semicircle’s perimeter is equal to half of the circle’s circumference plus its diameter. The circumference of a circle is 2πr or πd. A semicircle’s perimeter is 1/2 (πd) + d or πr + 2r, here r is the radius. Examples. Example 1: Find out the area of the semicircle whose radius is 10cm. Solution: r = 14cm. Area of semi-circle = (πr 2)/2 brass steam whistles for saleTo find the perimeter of a semicircle, we need to know either the diameter or radius of the circle, as well as the arc length of the semicircle. The arc length of the semicircle can be thought of as half the circumference of the circle. Since the circumference of a circle is C = πd or C = 2πr, where C is the … See more Since a semicircle is half a circle, we can derive its area equation by dividing the equation for the area of a circle by 2: where A is the area and r is the radius of the semicircle.
