Given:
The radii of circles are 14 cm and 7 cm.
To find:
The area of the shaded region.
Solution:
Area of a circle is
![Area=\pi r^2](https://tex.z-dn.net/?f=Area%3D%5Cpi%20r%5E2)
From the given figure, it is clear that
Area of shaded region = Area of larger circle - Area of smaller circle
= ![\pi (14)^2-\pi (7)^2](https://tex.z-dn.net/?f=%5Cpi%20%2814%29%5E2-%5Cpi%20%287%29%5E2)
= ![\dfrac{22}{7}\times 14\times 14-\dfrac{22}{7}\times 7\times 7](https://tex.z-dn.net/?f=%5Cdfrac%7B22%7D%7B7%7D%5Ctimes%2014%5Ctimes%2014-%5Cdfrac%7B22%7D%7B7%7D%5Ctimes%207%5Ctimes%207)
= ![616-154](https://tex.z-dn.net/?f=616-154)
= ![462](https://tex.z-dn.net/?f=462)
Therefore, the area of the shaded region is 462 sq. cm.
The general equation of a line is y = mx +b.
m is equal to the slope, so for this problem it is m = -3
b is equal to the y-intercept (the y-point when x = 0) so according to this since it passes through (0, -2), x=0 at y = -2
The equation of the line is: y = -3x - 2
All we have to do to find the solution to the system of equations represented by the given graph is find the two lines' intersection point. Here, we can see that the two lines intersect at the point (3, 4). Hence, the solution to the systems of equations is (3, 4). Hope this helps!
