WebFeb 1, 2024 · Use the diameter to find the area of the semicircle. The formula for the area of a circle is. A = π r2. Because the diameter is 14 meters, then the radius must be 7 meters. So sub in 7 for r and solve for Area. Ao = π r2. Ao = π (7)2. Ao = 49 π square meters ← exact answer. Ao = 153.93 square meters ← rounded to the nearest hundredth.

WebFormula – How to calculate the circumference of a semicircle from the radius. π is approximately equal to 3.1415926535. Circumference = (π x Radius) + (2 x Radius) Example. A semicircle has a radius of 10. Circumference = (π x 10) + (2 x 10) = (3.14159 x 10) + (2 x 10) = 314.159 + 20 = 334.159. Method #2 – Circumference from the Diameter ... WebSo we derive the formula for the area of a semicircle as $(\pi r^{2})/2$, which is half the area of a circle. Also, the surface area of the semicircle formula is the same as the area of the semicircle formula. Area of semicircle $=\frac{\pi r^{2}}{2}$ Fun Facts! Semicircle is obtained by cutting the circle into two exactly equal halves. WebA semicircular closed region has a perimeter equal to half of the circumference of a circle plus its diameter.
