<u>Given</u>:
The radius of the circle is 10 cm
The central angle of the circle is (360 - 90)° = 270°
We need to determine the area of the composite figure.
<u>Area of the composite figure:</u>
The area of the figure can be determined using the area of the sector formula.
Thus, we have;
![A=(\frac{\theta}{360}) \times \pi r^2](https://tex.z-dn.net/?f=A%3D%28%5Cfrac%7B%5Ctheta%7D%7B360%7D%29%20%5Ctimes%20%5Cpi%20r%5E2)
Substituting
and
in the above formula, we get;
![A=(\frac{270}{360}) \times (3.14) (10)^2](https://tex.z-dn.net/?f=A%3D%28%5Cfrac%7B270%7D%7B360%7D%29%20%5Ctimes%20%283.14%29%20%2810%29%5E2)
Simplifying, we get;
![A=(\frac{270}{360}) \times (314)](https://tex.z-dn.net/?f=A%3D%28%5Cfrac%7B270%7D%7B360%7D%29%20%5Ctimes%20%28314%29)
Multiplying, we get;
![A=\frac{84780}{360}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B84780%7D%7B360%7D)
Dividing the terms, we get;
![A=235.5 \ cm^2](https://tex.z-dn.net/?f=A%3D235.5%20%5C%20cm%5E2)
Thus, the area of the composite figure is 235.5 cm²
Hence, Option C is the correct answer.
Answer:
you would double it A 0 12.50 25.00
