You can  put this solution on YOUR website! Write an equation in standard form for the circle that statisfies these conditions 
center(0,7) tangent to x-axis 
** 
If you make a rough sketch of given points, you will see that the radius=7 
Standard form of equation for a circle: (x-h)^2+(y-k)^2=r^2, (h,k)=(x,y) coordinates of center, r=radius. 
Equation of given circle 
x^2+(y-7)^2=7^2 
x^2+(y-7)^2=49
