Question

The circle below is centered at the point (-3.5, 6) and has a radius of length 1.6. Write the equation for the circle.

Answer 1

(x – 3.5)^2 + (y +6)^2 = 1.6^2

Explanation:

(x – h)^2 + (y – k)^2 = r^2 is the equation of a circle

plug the radius in for r

switch the signs of the center points and plug them in for h and k
