Answer:
40.192 centimeters
Step-by-step explanation:
The circumference of a circle can be found using:
c= pi* diameter
First, we must find the diameter. The diameter of a circle is twice it’s radius.
d=2*radius
The radius of the circle is 6.4 centimeters. Substitute 6.4 for the radius.
d=2*6.4
d=12.8
Now we know the diameter. We can substitute 12.8 for diameter in the circumference equation.
c=pi*diameter
c=pi*12.8
We also know we are using 3.14 for pi, so we can substitute 3.14 for pi.
c=3.14*12.8
c=40.192
Use appropriate units: centimeters
c=40.192 centimeters
The circumference is 40.192 centimeters.

Answer:
y = -8|x| + 6
Step-by-step explanation:
y = a|x-b| + c; (b,c) = vertex and a = constant
y = a|x-0| + 6 -->
y = a|x| + 6 -->
-2 = a|-1| + 6 -->
-2 = a + 6 -->
-8 = a -->
y = -8|x| + 6
