What is the equation of the circle in graphing form? The center of a circle is at (-2, -7) and its radius is 36?
I'm not to sure what is meant by 'graphing form' as you have the centre and radius required to draw the circle. The radius of 36 also seems large.
However , the standard form of the equation of a circle is :
#color(red)(|bar(ul(color(white)(a/a)color(black)( (x - a)^2 + (y - b)^2 = r^2 )color(white)(a/a)|)))#
where (a , b) are the coordinates of centre and r , the radius.
here a = -2 , b = -7 and r = 36
substituting these values into the standard equation to obtain.
# (x + 2)^2 + (y + 7)^2 = 36^2 #
