Question

Whats the equation of a circle with the center point of 1, -1 and a radius of. 5

Answer 1

Explanation:

For this problem, we need to use the fact that the circle with center (h,k) and radius r is (x-h)^2 + (y-k)^2 = r^2.

This gives us that the equation of the circle is (x-1)^2 + (y-1)^2 = 25.
