Step-by-step explanation:
5x-4y=8, 3x+2y=8: ![y=\frac{8}{11}, x=\frac{24}{11}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B8%7D%7B11%7D%2C%20x%3D%5Cfrac%7B24%7D%7B11%7D)
We are given a circle with a partially shaded region. First, we need to determine the area of the whole circle. To do this, we need the measurement of the radius of the circle:
Use the Pythagorean theorem to solve for the other leg of the right triangle inside the circle:
5^2 = 3^2 + x^2
x = 4
The radius is 4 + 1 cm = 5 cm
So the area of the circle is A = pi*r^2
A = 3.14 * (5)^2
A = 25pi cm^2
To solve for the area of the shaded region:
Ashaded = Acircle - Atriangles
we need to solve for the area of the triangles:
A = 1/2 *b*h
A = 1/2 *6 * 5
A = 15 cm^2
Atriangles = 2 * 15
Atriangles = 30 cm^2
Ashaded = 25pi - 30
