MCQ

Coordinates of centre and radius of the circle $(x-3)^2+(y+4)^2=25$ are respectively:

A
$(3,4), 25$
B
$(-3,4), 5$
✓
$(3,-4), 5$
D
$(3,-4), 25$

✓

Answer

Correct option: C.

$(3,-4), 5$

$(3, -4), 5$

Solution:
$=(x-3)^2+(y+4)^2=25$
$=(x-3)^2+(y-(-4))^2-(5)^2$
$=(x-4)^2+(y-k)^2-(r)^2$
$=r=5(h, k)=(3,-4)$
