Write an equation of the circle with center (-3, 4) and radius 6.

(x+3) ² + (y-4) ²=36.

Step-by-step explanation:

For this, we need to use the equation of a circle which is:

(x-h) ² + (y-k) ² = r²

Simply substitute the center values for 'h, k', and the radius for 'r'.

This will give you:

(x+3) ² + (y-4) ²=36.
