Please Help! <3 What is the center and the radius of a circle with the following equation.

So the center is (0,-4) and the radius is 6

Step-by-step explanation:

We can write the equation of a circle as

(x-h)^2 + (y-k) ^2 = r^2  where (h,k) is the center and r is the radius

We have

(x)^2 + (y+4) ^2 = 36

(x-0)^2 + (y- -4) ^2 = 6^2

So the center is (0,-4) and the radius is 6

Centre: (0,-4)

Radius: 6

Step-by-step explanation:

(x - h)² + (y - k)² = r²

(x - 0)² + (y - (-4))² = 6²

Centre: (0,-4)

Radius: 6

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
