C-08-Q158mediumsingle_mcq

If two circles intersect each other externally and one diameter is $8$ cm while the other radius is $4$ cm, the distance between their centres is—

a $0$
b $4$
c $8$
d $12$

ব্যাখ্যা

The first circle has diameter $8$ cm, so its radius is $4$ cm, and the second radius is also $4$ cm. For external tangency the centre distance equals the sum of radii, $4+4=8$ cm.
