Question

The area of the circle x^2+y^2-8x-24=0

Answer 1

pi*r^2

Answer 2

Thanks :)

Answer 3

find r from the equation and apply \[\Pi r ^{2}\]

Answer 4

What is the value of r here??

Answer 5

\[r=2\sqrt{10}\]

Answer 6

How ??

Answer 7

\[40\pi \]

Answer 8

the general equation of a cirle is \[(x-h)^{2} + (y-k)^{2} = r ^{2}\] compare this to your equation and find "r"

Answer 9

\[r=\sqrt{g^2+f^2-c}\]

\[r=\sqrt{16-(-24)}=\sqrt{16+24}=\sqrt{40}\]

Answer 10

I know that..

I am asking find here proper value for r..

Answer 11

r is r come on ?

Answer 12

Are you not getting 8 ??

Answer 13

So 40pi is final :D

Answer 17

Ha ha ha ha..

Answer 18

lol :P

Answer 19

good going @waterineyes

Answer 20

in this case compare your equation to \[x ^{2} + y ^{2} + 2gx + 2fy + c = 0\] where \[r = \sqrt{g ^{2} + f ^{2} - c}\]

Answer 21
