If the equation of the circle with centre at (h, k) and radius r is x² + y² = r². Then, h and k respectively are

a. (1, 1)
b. (-1, -1)
c. (0, 0)
d. None of these

Respuesta :

Answer:

  c. (0, 0)

Step-by-step explanation:

You want the coordinates of the center of the circle x² +y² = r².

Circle equation

The standard form equation for a circle is ...

  (x -h)² +(y -k)² = r² . . . . . . center at (h, k)

When we have x-h =x, then h=0. Similarly, when y-k=y, then k=0.

The values of (h, k) for the given circle are (0, 0), choice C.
