What is the general form of the equation of the given circle with center A
1 answer:
Your answer would be option C. x² + y² + 6x - 24y + 128 = 0.
This is because the formula for the equation of a circle is (x - [x coordinate])² + (y - [y coordinate])² = radius², so you have to substitute in the coordinates and the radius, and then expand and simplify. I have done this in paper as it is easier to write than type, but let me know if you would like me to explain any part of it.
I hope this helps!

Answer:
r = 7 ft
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Here C = 43.96 , then
2πr = 43.96 ( divide both sides by 2 × 3.14 ← for π )
r = =
= 7 ft
