A circle has a radius of square root of 13 units and is centered at (-9.3,4.1) what is the equation of this circle

(x + 9.3) ^2 + (y - 4.1) ^2 = 13

Step-by-step explanation:

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

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

Putting your numbers into this form gives ...

(x - (-9.3)) ^2 + (y - 4.1) ^2 = (√13) ^2

(x + 9.3) ^2 + (y - 4.1) ^2 = 13
