13.) Find the area of the shaded region if the side length of the square is 8 in.
sladkih [1.3K]

Answer:

<h3>Area of shaded region = 6.88 square inches</h3>

Step-by-step explanation:

Area of shaded region

  When we subtract the area of the circle from the area of square, we get the area of the 4 corners. When we divide that by 2, we get the area of 2 corners(shaded).
\sf \boxed{\text{Area of the shaded region =$\dfrac{Area \ of \ square - area \ of \ circle}{2}$}}

<h3>Square: </h3>

Area of square = side *side

                          = 8 * 8

                          = 64 square inches

<h3>Circle:</h3>

     diameter of the circle = side of the square

                                     d = 8 in

                                      r = 8/2 = 4 in

   \sf \text{Area of circle = \pi r^2}  Area of circle = πr²

                            = 3.14 * 4 * 4

                            = 50.24 square inches

\sf \text{Area of shade region = \dfrac{64 - 50.24 }{2}}

\sf \text{Area of the shade region = $\dfrac{64 - 50.24}{2}$}

                                       \sf = \dfrac{13.76}{2}\\\\= 6.88 \ square inches

astraxan [27]

Answer:

Step-by-step explanation:

hello,

f(x)=-x^2+3x+5\\g(x)=x^2+2x \ \ \ so \ \ \ \\\(f+g)(x)=f(x)+g(x)=-x^2+3x+5+x^2+2x=5x+5\\

this is a line, graph below

hope this helps

How to determine the direction of a vector?
Ira Lisetskai [31]
Using the (x,y) coordinate or unit circle concept, find which quadrant the vector is in by the signs of x and y.  Take the arcTan( y/x) for its reference angle, then draw the vector in that quadrant.
