i got its c

jdoe0001 · Answer

hmmm that looks like a cylinder,no a circle per se

and where are the like-equations?

anonymous · Answer

$$volume=\pi r^2 h=\pi *6^2*13=? cubic units$$

jdoe0001 · Answer

you mean you guessed c?

anonymous · Answer

no the answer is c

jdoe0001 · Answer

though the idea is to solve it
and .... I don't see any equations to compare against
and I don't see the cirlce
so I don't see how you get "c"

if looking for the volume of that cylinder, well, recheck your value

jdoe0001 · Answer

hmmm  tis $\pi$ based... anyhow, the choices do not match the question
