Answer:
c
Step-by-step explanation:
Find the diameter of circle using pythagoras
d = √(Δx² + Δy²)
d = √((7-1)² + (-6-2)²)
d = √(6² + (-8)²)
d = √100
d = 10
The diameter is 10
Find the circumference
c = π × d
c = 3.14 × 10
c = 31.4
Subtracting 7 and dividing by -3 on both sides shows us that y = -9
The answer without any certain formula would be 18.211
A possible answer for #12 could be 12.
