Answer:

x^2 + y^2 = 225.

Step-by-step explanation:

The general form is x^2 + y^2 = r^2    where r = the radius of the circle.

The radius is 15 so the equation is x^2 + y^2 = 15^2.

That is x^2 + y^2 = 225.

The equation is x² + y² = 225.

What is standard equation of a circle?

The standard equation of a circle with center at (h, k) and radius r is

(x - h)² + (y - k)² = r²

Here, (h, k) is (0, 0) and r = 15

Substitute the values,

x² + y² = 15²

Thus, the equation is x² + y² = 255.
