Answer:
(1/2, 1)
2
Step-by-step explanation:
x² + y² − x − 2y − 11/4 = 0
x² − x + y² − 2y = 11/4
Complete the squares.
x² − x + 1/4 + y² − 2y + 1 = 11/4 + 1/4 + 1
(x − 1/2)² + (y − 1)² = 4
The center of the circle is (1/2, 1) and the radius of the circle is 2.
You are looking for the circumference. which is C(circumference)=

x r (radius)
the radius is =to half of the diameter.
c=56.55
The equation would be -5+(-12), so the answer would be -17 :)
