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

Explanation:

we know that

The formula to calculate the area of sector is equal to


A_s=(x)/(y)A_c

where


A_s ----> is the area of sector


x ----> is the central angle measure of the sector in degrees


y ---> total angle measure of a circle in degrees


A_c ---> represent the area of the circle

see the attached figure to better understand the problem

we have


x=m\angle ZYX=\theta^o ----> central angle of sector ZYX


y=360^o ----> total angle measure of a circle in degrees


A_c=\pi r^(2) ---> represent the area of the circle

substitute in the formula


A_s=(\theta^o)/(360^o) (\pi r^(2))

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

In the figure, angle ZYX is measured in degrees. The area of the shaded sector can-example-1
