1. Write the equation for a circle with center (1/2,3/7) and radius √13.

(x - 1/2) ^2 + (y - 3/7) ^2 = 13

Step-by-step explanation:

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

(x - h) ^2 + (y - k) ^2 = r^2

Filling in the given values results in the equation shown in the Answer space above.
