Question

6) Graph the circle with center at (-1, 2) and diameter 12. Label the center and at least four points on the circle. Write the equation of the circle.

Answer 1

(h,k) is center and

equation for circle is

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

so h =-1 and k =2

the diameter = 12

r or the radius is d/2

12/2 =?

can you plug theses in
