Hello :
<span>an equation is : y=ax+b a is a slope</span>
Answer:x=-2.30
Step-by-step explanation:
6.95x+16.2-2.36x=3.2x+13
6.95x-2.36x+16.2=3.2x+13
4.59x+16.2=3.2x+13
4.59x-3.2x+16.2=13
1.39x+16.2=13
1.39x+16.2-16.2=13-16.2
1.39x=-3.2
1.39x÷1.39=-3.2÷1.39
X=-2.30
Circumference: 18.84 m
Area: 28.26
Explanation
For circumference, use the formula *d, where d=the diameter(the radius times 2).
For area, use the formula , where r=the radius. Make sure to square the radius first before multiplying by pi!
A good way to remember these formulas is Cherry(circumference) Pi() is Delicious(diameter) and Apple(area) ("are too")
