Question

MEDALS AND FANED MEDALS AND FANED




Arrange the circles (represented by their equations in general form) in ascending order of their radius lengths.

Answer 1

i solve one and try other

Answer 2

x*x+y*y-2x+2y-1=0
(x*x-2*x*1+1)+(y*y+2*y*1+1)-1-1-1=0 since i add 1 in both brakets
(x-1)^2+(y+1)^2=3

Answer 3

here radius=sqrt(3)

Answer 4

the first one reduis = sqrt(3)
