Answer:

  • area: 78.5 square units
  • circumference: 31.4 units

Step-by-step explanation:

The diameter is the difference between x-coordinates of the end points of the horizontal line through the center:

  d = 12 -2 = 10

The radius is half that, so is ...

  r = d/2 = 10/2 = 5

The area is given by ...

  A = πr^2 = π(5^2) = 25π ≈ 78.5 . . . . square units

The circumference is given by ...

  C = πd = 10π ≈ 31.4 . . . . units
