How do you write an equation for a circle with center at (7, 3) and a diameter of 24?
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 ,3) hence a = 7 , b = 3 and r = 12
Substitute these values into the standard equation.
#rArr(x-7)^2+(y-3)^2=144" is the equation of the circle"#
