Answer:
42.43
Step-by-step explanation:
Given:
A circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle.
Question asked:
What is the area of the shaded region as shown in the figure ?
Solution:
First of all calculate area of circle and then area of rectangle:-
![Area\ of\ cirle=\pi r^{2}](https://tex.z-dn.net/?f=Area%5C%20of%5C%20%20cirle%3D%5Cpi%20r%5E%7B2%7D)
![=\frac{22}{7} \times5\times5\\ \\ =\frac{550}{7}\\ \\=78.571\ cm^{2}\\](https://tex.z-dn.net/?f=%3D%5Cfrac%7B22%7D%7B7%7D%20%5Ctimes5%5Ctimes5%5C%5C%20%5C%5C%20%3D%5Cfrac%7B550%7D%7B7%7D%5C%5C%20%20%5C%5C%3D78.571%5C%20%20%20cm%5E%7B2%7D%5C%5C)
<u>As here length an width both are 11 cm, we can say that this is a square.</u>
<u />![Area\ of\ square=(Side)^{2}](https://tex.z-dn.net/?f=Area%5C%20of%5C%20square%3D%28Side%29%5E%7B2%7D)
![=11\times11=121\ cm^{2}](https://tex.z-dn.net/?f=%3D11%5Ctimes11%3D121%5C%20cm%5E%7B2%7D)
Now, area of shaded region = Area of square - Area of circle
= 121 - 78.571 = 42.429 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
Therefore, the area of the shaded region will be 42.43 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
The answer is 1 bc the solution is (1,-3)
Answer:
the answer will be 366:81
Step-by-step explanation:
you will find value of ratio 3:18
=6
then divide 366:61
=6
D is correct. U is incenter of the triangle.
