Answer:
The central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector
Step-by-step explanation:
we know that
The formula to calculate the area of sector is equal to
[tex]A_s=\frac{x}{y}A_c[/tex]
where
[tex]A_s[/tex] ----> is the area of sector
[tex]x[/tex] ----> is the central angle measure of the sector in degrees
[tex]y[/tex] ---> total angle measure of a circle in degrees
[tex]A_c[/tex] ---> represent the area of the circle
see the attached figure to better understand the problem
we have
[tex]x=m\angle ZYX=\theta^o[/tex] ----> central angle of sector ZYX
[tex]y=360^o[/tex] ----> total angle measure of a circle in degrees
[tex]A_c=\pi r^{2}[/tex] ---> represent the area of the circle
substitute in the formula
[tex]A_s=\frac{\theta^o}{360^o} (\pi r^{2})[/tex]
therefore
The central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector
