Answer 1

Equation of a circle :
(x - h)2 + (y - k)2 = r2
where h and k are the x- and y-coordinates of the center of the circle and r is the radius.
can u get the answer now ?

Answer 2

A

Answer 3

check agian x,y coordinates ..

Answer 4

B? I'm not sure, I never understood this formula. @Eyad

Answer 5

Just apply the rule its easy ,why did u choose a before ?

Answer 6

It's not easy to me. And I just chose it cause I thought it matched in my brain.

Answer 7

lol
The standard equation is :(x - h)2 + (y - k)2 = r2
your equation : (x-1)^2 + (y+3/2)^2=9/4
Lets translate it according to the standard equation :
1- h and k are the x- and y-coordinates
Therefore (1,-3/2) are the x,y coordinates=center of da circle
2-r is the radius of the circle and it should be r^
so r^2=9/4 ,r=3/2

_______
(1,-3/2) are the x,y coordinates=center of da circle ,and r=3/2
______________
What do u think ?which choice ?

Answer 8

B

Answer 9

Are u kidding ?

Answer 10

The radius in b is 9/4 ,I wrote the answers can't u match :D

Answer 11

I'm retarded.. ok ok... I hate this formula..

Answer 12

lol ,no i want to hear the answer from u ,what do u think ?which choice got (1,-3/2) are the x,y coordinates=center of da circle ,and r=3/2 ???

Answer 13

so then C

Answer 14

c got -1 ,and its 1 ...
AND DONT SAY D ---X
So whats remain ?

Answer 15

I'm confused... hahahaha. so A?!?
