A...area = 379.94 in^2

π=3.14

r...radius

d...diameter= 2r

A= π*r^2

r^2=A/π

r=√(A/π) = 11 in

d=2r =22 in

Answer:

Bisecting an angle ⇒ answer a

Step-by-step explanation:

* <em>Lets revise the steps of bisecting an angle</em>

- <em><u>How to construct a bisector of angle XYZ</u></em>

1. Open the compass to any width, and place its pin at the angle’s

   vertex Y and draw an arc cuts the two rays of the angle YX and YZ

   at two points M and N respectively

2. Open the compass to another width and place its pin at M and draw

    an arc between the two rays YX and YZ

3. Without changing the width of the compass place its pin at N and

   draw another arc intersects the arc from M at point Q

4. Join YQ which is the bisector of angle XYZ

* <em>Now lets compare these steps by the steps of the question</em>

∵ The vertex of the angle ABC is A represented by Y

∵ The rays of the angle AC and AB represented by YX and YZ

∵ Points D , E represented by points M , N

∴ The construction is " Bisecting an angle "

....pls help me :((((((
Rina8888 [55]

Answer:

y= -7

Step-by-step explanation:

So first distribute the 8

4=8y+32-4y

now combine like terms (the -4y+8y)

4=32+4y

Subtract 32 on both sides to isolate 4y

-28=4y

now divide 4 on both sides to isolate Y

-7=y

so y= -7
