MEDAL + FAN

a circle has its center at (-3,2) and a radius of 5 units.what is the equation of the CIRCLE?

Answer 1

what is the generall form equation of a circle?

Answer 2

THATS all they ask me

Answer 3

whoops, meant center-radius form

Answer 4

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

Answer 5

can we do it together?

Answer 6

you haven't even bought me dinner yet.

Answer 7

just plug in the information they've given you. you have the center (h,k) = (-3,2)
plug that into the \(\large (x-h)^2+(y-k)^2=r^2\) equation

Answer 8

for example if our circle was at 1,3 it'd look like \((x-1)^2 + (y-3)^2\)
(2,-4) would look like \((x-2)^2 + (y--4)^2=(x-2)^2 + (y+4)^2\)

Answer 9

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

Answer 10

yeah, good job. now what is r?

Answer 11

5

Answer 12

??

Answer 13

yeah!!

Answer 14

so what do we do now?

Answer 15

nothing. we have the equation

Answer 16

can you write it out for me so i can see how it looked squared

Answer 17

just in case it isn't clear,
\((x--3)^2 + (y-2)^2=5^2\) simplify it yourself

Answer 18

no help and i paid for dinner?

Answer 19

you bought dinner just to get into my reputably loose pants

Answer 20

what is (x--3)? what is 5^2?

Answer 21

x3+25?

Answer 22

x3?

Answer 23

?

Answer 24

x3+25?
what does that even mean? I asked you for 2 different expressions not a sum

Answer 25

can you help me

Answer 26

I've given you the answer bro \(\huge (x--3)^2 + (y-2)^2=5^2\)

Answer 27

thanks
