Acircle is inside a square as shown.

what is the area of the shaded region?

use 3.14 for π .

enter your answer as a decimal in the box.

Hi there!

To find the shaded area, we need to subtract the area of the circle from the area of the square. First, let's find the area of the square by multiplying 8 x 8, which gives us 64 or the area of the square. Next, we need to find the area of the circle. We know that the radius is 4 (half of the diameter, 8), so this will be easy. Plug it into the formula and solve: pi x 4^2 | 16pi. Now, all we have to do is subtract 16pi from 64. This leaves us with 13.735 for the shaded area (can round decimal to tenth = 13.7, hundredth = 13.74). 

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
