Question

A circle has a center at A (-3,4) and radius of 4 units. What is the equation of the circle? Show work!

Answer 1

Answer:

The equation of the circle is (x+3)^2 + (y-4)^2 = 16.

Step-by-step explanation:

The equation of a circle can be calculated if the center and the radius are known. The equation of a circle is given by  (x-h)² + (y-k)² = r²

Where  (h, k) = center coordinates  and r = radius.
