Answer:
Radius of the given circle is r = 2.
Step-by-step explanation:
Given equation of the circle is
.
Now we need to find the radius of the given circle
.
To find that let's compare with the formula of the circle with is
, where r is the radius.
We get 
take square root of both sides.

Hence radius of the given circle is r = 2.
