The center of a circle is at (0,0), and the radius of the circle is 3-2. Which equation represents the circe?

9514 1404 393

  B.  x² +y² = 18

Step-by-step explanation:

The standard form equation of a circle with center (h, k) and radius r is ...

  (x -h)² +(y -k)² = r²

For (h, k) = (0, 0) and r = 3√2, the equation is ...

  (x -0)² +(y -0)² = (3√2)² = 3²·2

  x² +y² = 18

there are no figures how am i supposed to answer this question

step-by-step explanation:

answer: the common difference is -0.10
