Formula

#
Formula principal
A=r22(θ−sin⁡θ)A = \frac{r^2}{2}(\theta - \sin\theta)

Como funciona: A area do segmento e a area do setor menos a area do triangulo formado pelos dois raios e a corda.

Exemplo Resolvido

Raio 10, angulo 90 graus: Area do setor = (pi x 100 x 90)/360 = 78,54 Area do triangulo = (100 x sin(90))/2 = 50 Area do segmento = 78,54 - 50 = 28,54 unidades quadradas.

Perguntas Frequentes

O que e um segmento circular?

E a regiao entre uma corda e o arco que ela delimita no circulo.

Qual a diferenca entre setor e segmento?

O setor e a "fatia de pizza" (duas linhas retas do centro). O segmento e a regiao entre a corda e o arco (sem as linhas do centro).
