How do you write an equation for a circle with center (3,0) and the radius is 1?
The standard form of the equation of a circle is.
where (a ,b) are the coordinates of the centre and r, the radius.
here a = 3, b= 0 and r = 1
substitute these values into the equation.
#rArr(x-3)^2+y^2=1" is the equation of the circle"#
