What is a semicircle?

A semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180°. It has only one line of symmetry. In non-technical usage, the term "semicircle" is sometimes used to refer to a half-disk, which is a two-dimensional geometric shape that also includes the diameter segment from one end of the arc to the other as well as all the interior points.

How to Calculate Area of a semicircle?

Area of a semicircle calculator uses Area=(pi*Radius^2)/2 to calculate the Area, The Area of a semicircle formula is defined as A=pi*r^2/2 where r is radius and A is area of semi-circle. Area and is denoted by A symbol.

How to calculate Area of a semicircle using this online calculator? To use this online calculator for Area of a semicircle, enter Radius (r) and hit the calculate button. Here is how the Area of a semicircle calculation can be explained with given input values -> 0.050894 = (pi*0.18^2)/2.

FAQ

What is Area of a semicircle?
The Area of a semicircle formula is defined as A=pi*r^2/2 where r is radius and A is area of semi-circle and is represented as A=(pi*r^2)/2 or Area=(pi*Radius^2)/2. Radius is a radial line from the focus to any point of a curve.
