Question 2: Find the area and the circumference of C to the
nearest tenth

9514 1404 393

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

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
