Semicircle Calculator. Calculations at a semicircle. Radius and diameter refer to the original circle, which was bisected through its center. Enter one value and choose the number of decimal places. Then click Calculate.
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.
The area of a semicircle is equal to half of the area of the whole circle. So the area of a semicircle is ½ πr 2 , where r is the radius of the circle. How to Find the Area of a SemiCircle Support
The semi-circle area is calculated using the formula: \ [ \text {Area} = \pi r^2 \frac {a} {360} \] where: \ (r\) is the radius of the circle, \ (a\) is the arc angle in degrees (for a semi-circle, this is always 180 degrees).
If the radius value is known, it is easy to find the area of a semicircle. For example, if the radius value is 7 cm, then the area of a semicircle is A = (½)(3.14)(7)(7)
