Question

Find the equation of the circle whose center and radius are given.
center ( 5.6), radius = 3

Answer 1

(x-5)² + (x-6)² = 9

Explanation:

Remember that the equation of a circle is (x - h)² + (x - k)² = r², with r being the radius and (h,k) being the center point of a circle.

Since we are already given r and (h,k), all we need to do is plug them into the formula to find our equation.
