How do you find the equation of the circle given center at (7, 0) and a radius of 10?
The standard form of the equation of a circle is.
where (a ,b) are the coordinates of the centre and r, the radius.
here centre = (7 ,0) hence a = 7 , b = 0 and r = 10.
Substitute these values into the standard equation.
#rArr(x-7)^2+y^2=100" is the equation of the circle"#
