Answer:
(A)
Step-by-step explanation:
The standard form of the equation of a circle is given as:

Simplifying the above given equation, we get




which is the required general form of the equation.
Hence, option A is correct.
Answer:
P = 3
Step-by-step explanation:
L = 4*w
P = 27 + w
P = 2*L + 2*w = 27 + w
2L = 2*(4w) = 8w
Put that into the perimeter formula (the first one.)
P = 8w + 2w = 27 + w
10w = 27 + w Subtract w from both sides
9w = 27 Divide by 9
w = 27 / 9
w = 3
You should find the Length just so you can check it.
L = 4w
L = 4*3
L = 12
Check
P = 2L + 2w
P = 2*12 + 2*3 = 30
P = 27 + w
P = 27 + 3
P = 30 and everything checks.
Answer:
If I had to take an educated guess I'd say 126° but I'm not 100% sure.
