Question

Write the equation of a circle with a center at (-1,2) and a radius of 7

Answer 1

Answer:

$(x+1)^2+(y-2)^2=49$

Step-by-step explanation:

The standard form for the equation of a circle is $(x-h)^2+(y-k)^2=r^2$ where  r  is the radius, and the center is (h, k).

(h, k) = (-1, 2),  r = 7

$(x-(-1))^2+(y-2)^2=7^2\\\\(x+1)^2+(y-2)^2=49$
