Need help ASAP -- Write the equation of the circle. (picture included)

Answer 1

you need a center point and a radius .... any ideas what those would be?

Answer 2

center: (3, 0)
radius: im guessing is 5 ??

Answer 3

3,0 seems fair

dont guess at the radius, its clearly available to you in the picture, just count from center upwards

Answer 4

from 3 to ....

Answer 5

oh the radius is 6

Answer 6

6 is the radius, good

now, what is your best attempt at the equation using these parts? give it your best shot

Answer 7

we want all the points (x,y) that are a certain distance, 6 units, from the center point, (3,0):

all we need to do is use the distance formula to define these things

Answer 8

(x - 3)^2 + (y^2) = 36 ?

Answer 9
