Question

Give the center and radius of the circle (x + 2)2 + (y - 4)2 =36

Answer 1

Answer:

B. Center: (-2, 4)

Radius: 6

Step-by-step explanation:

The equation of a circle:

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

Where

$(h,\ k)$ - center

$r$ - radius

We have the equation

$(x+2)^2+(y-4)^2=36\\\\\bigg(x-(-2)\bigg)^2+(y-4)^2=6^2$

Therefore

the center is (-2, 4)

the radius is 6
