Simply use the formula they give you. For question 6, 4 is the radius. So the area of the circle is 4pi. Now for seven you do the same thing, but they gave you the diameter instead and it’s a half circle. So try that one on your own. Let me know if you get stuck
Answer:
Δ HGI ≅ ΔEDF
Step-by-step explanation:
Given:
Δ DEF ≅ Δ GHI
From the given congruence statement we can figure out the corresponding sides that are congruent.
The arrangement shows:

So the rearranged statement can be written as:
ΔEDF ≅ Δ HGI
or
∴ Δ HGI ≅ ΔEDF

<u>Steps for equation/answer :</u>
1.Divide both sides by 3.
4x+9= 111/3
2.Simplify 111/3 to 37.
4x+9=37
3.Subtract 9 from both sides.
4x=37−9
4. Simplify 37-9 to 28.
4x=28
5. Divide both sides by 4.
x = 28/4
6. Simplify 28/4 to 7
x=7
