Question

A circle has its center at (-1, 2) and a radius of 3 units. What is the equation of the circle?

Answer 1

Hello,

Answer D

(x+1)²+(y-2)²=9

Answer 2

Answer:

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

last option is correct.

Step-by-step explanation:

We have been given that

Center: (-1,2)

Radius :  3 units

We know that the standard form of the circle is given by

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

Here, h = -2, k = 2, and r=3

Substituting these values in the above formula, we get

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

Therefore, last option is correct.
