Answer:

Step-by-step explanation:
First, we'll find the length of the radius using distance formula and the coordinates (0,0) and (7,0)
Distance Formula = 
R = 
R = 
Radius = 7 units
<u><em>Now, Equation of circle:</em></u>

Where (a,b) = (0,0) So, a = 0, b = 0 and R = 7 units
=> 
=> 
This is the required equation of the circle.
