Question

When you are trying to find two points on a circle, how can you get a whole number??

Answer 1

do you mean passing through integer coordinates?

Answer 2

yes

Answer 3

When I plug in a random number, I am getting a decimal. I am not sure how to know the range of numbers to choose from..

Answer 4

just choose an integer x and solve for y AND hope for the best...

Answer 5

yes because circles pass through many more points that just integer coordinates. some circles don't pass through integer coordinates at all.

Answer 6

Oh, well do you think its ok if I end up with a decimal as my answer for a point on the circle?

Answer 7

and not the whole number?

Answer 8

I think someone on here said to not choose something bigger than the radius..

Answer 9

yes but i'd stick with an exact answer.

Answer 10

I'm having troubles getting an exact answer... you have to choose a number no bigger than the radius or something.. I have no idea.

Answer 11

yes, of course.

Answer 12

like for the equation.. (x-4)^2 + (y-2)^2 = 196.. I plugged in 18 and it was exact.. but I'm not sure how I did that.

Answer 13

let's examine that..

Answer 14

that is a circle centered at (4, 2) with a radius of 18...

Answer 15

-10 also works.. but I do not know I did that either.

Answer 16

Yes

Answer 17

do you mean radius of 14?

Answer 18

yes, i mean 14:
