C-08-Q120mediumsingle_mcq

In a circle with centre $O$ and $OB = 2.5$ cm, the perimeter of the (cyclic) figure $ABCD$ depends on—

athe centre only
bthe placement of $A,B,C,D$ on the circle of radius $2.5$ cm
conly the diameter
donly the chord lengths squared

ব্যাখ্যা

Once the radius is fixed at $2.5$ cm, the vertices $A,B,C,D$ can be placed anywhere on that circle, and the side lengths—and hence the perimeter—change with their positions. So the perimeter depends on where the four points sit on the circle, not on the centre or diameter alone.
