Answer:

D. 28.54

Step-by-step explanation:

To find the area of the shaded region, find the area of the circle and divide it in 4. This will the area of the portion with the triangle.

Now, find the area of the triangle and subtract the two. The resulting value will be the area of the shaded region.

Circle:

A = \pi r^2\\A = \pi 10^2\\A = 100 \pi\\A = 314

Divide by 4 for the area of the section with the triangle.

314/4 = 78.5

Triangle:

A = \frac{1}{2}bh\\A = 0.5 (10 )(10)\\A=0.5(100)\\A=50

Subtract the two, 78.5 - 50 = 28.5.

lutik1710 [3]

  It is not a function

Step-by-step explanation:

The plot shows (1, 1) and (1, 3) are both defined by the relation. It does not pass the "vertical line test", which requires the relation be single-valued everywhere.
