Answer:
The circle is centered at (-8,3) and has a diameter of 20 units
Step-by-step explanation:
we know that
The equation of a circle in center radius form is equal to

where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have

so
The center is the point (-8,3)
The radius is 
so
The diameter is two times the radius

therefore
The circle is centered at (-8,3) and has a diameter of 20 units
They are made by 1. 4 is made by 2, 8 is made by 2 and 4, 6 is made by 2 and 3.
Answer:
<u><em>Answer is below</em></u>
Step-by-step explanation:
<u><em>Evaluate for h=−8,w=20</em></u>
<u><em>9+20/5+(5)(-8)</em></u>
<u><em>So therefore your answer would be -27</em></u>
