The standard equation of a unit circle is

x²+y²=1

So, if we want a radius of 4, we need to square it.

so we have x²+y²=16

Answer:

x^2 + y^2 = 16

Step-by-step explanation:

The equation of a circle is given by

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

(x-0)^2 + (y-0)^2 = 4^2

x^2 + y^2 = 16
