El área de un círculo cuyo radio es 4 cm se puede calcular de la siguiente forma:

A=π×4×4=4^2π=16π

5

1. Calcula el área del sector circular determinado por un ángulo de 90°

6

Solucionamos

$\$ $S:90=16π:360$
$360\times S=16π×90$
$S=16π×\ \frac{90°}{360°}$
$S=16π×\ \frac{1}{2}$
$S=4π$

7

Para encontrar el área de un sector circular, se debe multiplicar la razón entre los ángulos por el área del círculo.

S=πr^2×\ \frac{a}{360°}
