Question

PLS HELP what would be the equation for this one?

Answer 1

Answer:

x^2 + y^2 = 25

Step-by-step explanation:

The standard form of a circle equation is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius.

We can see that the center is (0, 0) by looking at the graph, and the radius is 5 because it is marked. Plugging these in we get:

x^2 + y^2 = 25
