This semicircle area calculator determines the area of a half circle, as well as the circumference of a semicircle.
Area of a Semicircle Formula. Because a semicircle is exactly half of a circle, then the area of semicircle must be exactly half that of the area of a circle. By the way, the prefix semi- means half. That means, if the area of a circle is [latex]\large{A = \pi {r^2}}[/latex]
The area of a semicircle is defined as the space enclosed inside a half circle. Learn the formula and method to calculate the area of semicircle using solved examples.
To find the area of a semicircle, start by finding the area of the full circle using the formula πr^2, where r is the radius of the circle. If you don't know the radius, you can find it by dividing the diameter of the circle by 2.
A Semi-Circle is defined as half of the Circle or of its Circumference. Get the formulas of Area and Perimeter of Semi-circle with examples at BYJU'S.
The calculator will calculate the radius, arc length, area of sector, perimeter, and diameter of a semicircle, with step-by-step calculations displayed. This area of a semicircle calculator is specifically designed to calculate the area of semicircle.
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
