30 gru 2015 · We can solve for r to show an expression for the radius of a semicircle when given the area: A = πr2 2. 2A = πr2. 2A π = r2. r = √ 2A π. If given the diameter: The diameter, like in a normal circle, is just twice the radius. 2r = d. r = d 2.
The area of a semicircle is calculated using the formula: Area = 1/2 * π * r². What is the radius in a semicircle? The radius in a semicircle is the same as the radius of a circle. It’s the distance from the center of the semicircle to any point on its boundary.
Click the Find Area button. You will be given two answers for the area, one in terms of Pi (π) and the other answer as a decimal value. Area of a Semi Circle Formula. The area of a semicircle is equal to half of the area of the whole circle. So the area of a semicircle is ½ πr2, where r is the radius of the circle.
