"In regards to my question radius 2.6 yd

length 8.4, 3.14 I used that formula

and somewhere i went wrong ikeep coming up with the answer 68.5776 whichis none of the choices given."

Both of the responses above indicate

V=πr²h

which means that

volume = π × r × r × h

Your answer 68.5776 corresponds to

π × r × h, so it is 2.6 times smaller than the correct answer.

Please try again with the correct formula. If you have problems, please post a follow-up here.
