Answer:

7.73cm^2

Step-by-step explanation:

The equation for area of a circle is a= pie r^2. Now plug in pie as 3.14 and you radius which would be 3 because the image is showing the diameter as 6 and radius is half the diameter. The equation is now a=3.14 x3x3. The area of the circle would be 28.27cm^2.

Now we must find the area of the square. To do this multiple the diameter which is 6 times itself. 6x6=36. The area of the square is 36cm^2.

Now subtract the square area from the circle area. 36 - 28.27 = 7.73. The left over plywood would be 7.73cm^2.

I hope this helps! If you have anymore questions feel free to ask! :D

The rectangle below has a area x^2-x-72 square meters and a length of x+8 meters what expression represents the width of the rec

mixer [17]

ANSWER

$w = (x - 8)$

EXPLANATION

The given rectangle has area,

$A = {x}^{2} - x - 72 \: {m}^{2}$

It was given to us that, the length of the rectangle is l=(x+8)

To find the width, we need to factor, the expression for the area.

We split the middle term to get,

$A = {x}^{2} - 9x + 8x- 72$

We now factor by grouping;

$A = x(x - 9) + 8(x- 9)$

$A = (x + 8)(x - 9)$

We know that area of a rectangle is

$A = l \times w$

Hence the width of the rectangle is,

$w = (x - 8)$
