Answer 4

Well that is certainly less fun than a music video...

Answer 5

anywho, first you can find the radius by finding the distance between the two points. then choose the equation with the appropriate radius squared, and appropriate center

Answer 6

the generic form for a circle being (x-a)^2+(y-b)^2=r^2 where a and b are the x and y coordinates of your center point, and r is your radius

Answer 7

Equation of circle is (x-h)^2 +(Y-k)^2 = r^2 . where h, k are center and r is the radius.

Answer 8

Here r is the distance between the given two points.

Answer 9

the radius is 241

Answer 10

right?

Answer 11

almost right! in this case it would be the square root of 241. ergo 241 is the radius squared

Answer 12

r^2 = 241

Answer 13

is the answer C?

Answer 14

@abbie YES.

Answer 15

can you help me with a few more?

Answer 16

First try to find out the coordinate of the center of the circle.

Answer 17

is it (3,-2) ?

Answer 18

yes

Answer 19

Here ur radius is 3. which is the x-coordinate of the center. R u getting it ?

Answer 20

If u look into the figure , u can be sure that ,the line joining the center and the point (0,-2) , is the radius. it's length is 3 unit.

Answer 21

so is the answer A @mikurout

Answer 22

no it is B.
