This circle is centered at the origin, and the length of its radius is 5. What is the equation of the circle?

Step-by-step explanation:

The equation of a circle is given in the form;

(x-a)² + (y-b)² = r²

Where, (a,b) is the center of the circle and r is the radius of the circle;

In this case; the center is (0,0) and r is 5 units

Therefore;

The equation of a circle will be;

(x-0)² + (y-0)² = 5²

Giving us;

x² + y² = 5²
