Question

find the area of each shaded region: 90° 2 area= question help: video submit question

Explanation:

Step1: Recall area - of - sector formula

The formula for the area of a sector of a circle is $A=\frac{\theta}{360^{\circ}}\times\pi r^{2}$, where $\theta$ is the central - angle and $r$ is the radius.

Step2: Substitute values

Here, $\theta = 90^{\circ}$ and $r = 2$. So $A=\frac{90^{\circ}}{360^{\circ}}\times\pi\times2^{2}$.

Step3: Simplify

$A=\frac{1}{4}\times4\pi=\pi$.

Answer:

$\pi$
