write the standard form of the equation of the circle withthe given radius (8,0) and whose center is the origin
The given radius of (8,0) does not look right, since radius is a scalar, it should not have two components.
The standard form of the circle, centred at (x0,y0) with radius r is given by:
C : (x-x0)²+(y-y0)² = r²
