Question

write the equation of a circle that has a center of ( -3,1 ) and a radius 3 .( please help )

Answer 1

Answer:

The equation of the circle is:

$(x+3)^2+(y-1)^2=9$

Explanation:

The equation of a circle with center at (h, k) and radius r is given as:

$(x-h)^2+(y-k)^2=r^2$

For a canter (-3, 1) and radius 3, we have:

$(x+3)^2+(y-1)^2=3^2$
