Answer:
the answer is 31.42
Step-by-step explanation:
Answer:
work is attached and shown
Hello :
<span>f(x)=x²+4x-5
</span><span>The axis of symmetry for a function in the form f(x)=x^2+4x-5 is x=-2 :
</span>f(x) = (x+2)² + b
f(x) x²+4x+4+b= x² +4x-5
4+b= -5
b = -9
the vertex is : (2 , -9)
First, the area of the pizza then double it.
Area for a circle: Area =

* r^2
Plug in the values.
We will use 3.14 for

.
We need the radius. So half the diameter to get the radius.
18 / 2 = 9
Area = 3.14 * 9^2
Area = 3.14 * 81
Area = <span>254.34
</span>
Then multiply 2 to get the double the area.
254.34 * 2 = <span>508.68
</span>
So, the answer to this question is <span>D. 508.68 in. 2.</span>
