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 free area of a semicircle calculator helps you to find the area, parameter, arc length, diameter, and radius of a semicircle in a span of moments.
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 πr 2 , where r is the radius of the circle.
Formulas for Calculating Semicircle Properties. Here are the formulas for calculating each property of a semicircle: Radius (r): r = d / 2. Diameter (d): d = 2 * r. Arc Length (a): a = π * r. Perimeter (p): p = d + a. Area (A): A = (π * r^2) / 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.
Practice Problem: Calculate the Area of a Semicircle. Example: Find the area of a semicircle with a radius of 8cm. To use the area of a semicircle formula, you have to know the length of the semicircle’s radius, r, which the problem tells you is 8cm. So, r=8. Next, you can substitute r=8 into the formula as follows:
