Question

Find the equation of a circle given its point in the centre being (1,2)

Answer 1

hey newton, how do you copy and paste someone else's latex

Answer 2

(x-1)sqare+(x-2)square=r square

Answer 3

As far as I know, you can't on here, unless they send it to you before they render it in LaTeX.

Answer 4

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

Answer 5

how annoying

Answer 6

Then how do we go about solving for r?

Answer 7

well someone send an email to the coders

Answer 8

You can't solve for r... a circle with centre 1,2 is not unique.

Answer 9

Wait couldn't we just use another point close to it, say (1,3) and solve for r?

Answer 10

r is radius boy it s given ithink

Answer 11

You could try. It wouldn't work (at all), but you could try.
