The circle in the figure below has radius r. What is its equation in standard form?

Your figure does not show here.

However if it has center at
(a , b)
then it is

(x-a)^2 + (y-b)^2 = r^2

To find the equation of a circle in standard form, we need the coordinates of the center and the radius. However, the figure you mentioned is not given, so we don't have the required information to determine the equation. If you provide the necessary details or the figure, I will be able to help you further.

To find the equation of a circle in standard form, we need to know its center coordinates and radius. Unfortunately, we don't have the center coordinates given in the figure.

The equation of a circle in standard form is (x - h)^2 + (y - k)^2 = r^2, where (h, k) represents the coordinates of the center of the circle.

If you have the center coordinates of the circle, you can substitute them into this equation to determine the equation of the circle.

Without the center coordinates, it is not possible to determine the exact equation of the circle.
