Question

What is the equation for a circle
Center (-2, -5) radius =1

Answer 1

\[(x-h)^2+(y-k)^2=r^2\]

Answer 2

thanks but not quite what i was looking for

Answer 3

(h,k)

Answer 4

your h is -2, k is -5

Answer 5

so you plug it in then square your radius

Answer 6

\[(x+2)^2+(y+5)^2=1^2\]

Answer 7

THANKS

Answer 8

HOW BOUGHT this one with center (0,8) radius =8

Answer 9

well i showed you how to do it, wanna give it a shot?

Answer 10

its really just plugging in

Answer 11

ok so ( x + 0)2 + ( y+8)2 = 8 2

Answer 12

the only reason why i changed it to positive the first time was because the numbers were negative, so for the most part, you're correct!

Answer 13

\[x^2+(y-8^2)=8^2\]

Answer 14

Center ( 7, -3) radius =7

Answer 15

use the same formula
