PLEASE HELP
There’s a picture up!!!

(x-5)^2 + (y+4)^2 = 100

Step-by-step explanation:

The formula for the graph of a circle is . The center is (h, v). We are already given the that center is (5, -4) so we currently have .

Now we want to find the radius. We are given the center and a point that the circle passes through, so we can calculate the distance between them (which is the radius). We find that the radius is 10.

So our equation is

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
