semicírculo
Sign in to saveAlso known as semicircle
In mathematics (and more specifically geometry), a semicircle is a one-dimensional locus of points that forms half of a circle. It is a circular arc that measures 180° (equivalently, radians, or a half-turn). It only has one line of symmetry (reflection symmetry).

Semicírculo, na matemática (mais especificamente, na geometria), é uma forma geométrica bidimensional que forma metade de um círculo. O arco de um semicírculo mede 180°. Para calcular a área de um semicírculo, usamos a fórmula: A=π.r²/2
