Question

SOMEONE PLEASE HELP ASAP.
Find the equation of a circle with a center at (7, 2) and a point on the circle at (-2, -5).

Answer 1

so the formula you want to use is (x-h)^2+(y-k)^2=r^2

Answer 2

what do I plug in though?

Answer 3

Plug in your point for x and y

Answer 4

what is h and k?

Answer 5

wait, before you find the equation... we need to find the radius

Answer 6

since you are given two points

Answer 7

d = sqrt(x^2-x^1)^2 + (y^2-y^1)^2

Answer 8

tell me what you get for the radius

Answer 9

once you found the radius, you can plug in the radius into the equation for the circle

Answer 10

could you possibly plug in the numbers cause im confused

Answer 11

idk how to get the radius though

Answer 12

d = sqrt(-2-7)^2 + (-5-2)^2

Answer 13

130 right?

Answer 14

yes, now plug in 130 into the other formula
