Answer:

C. . II and III only

Step-by-step explanation:

Given:

I. V=s^3

II.V=πr^2h

III. V=Bh

From the above

I. V varies directly as cube of s

II. V varies jointly as square of r and h where π is the constant of proportionality.

III. V varies jointly as B and h

Therefore, the volume formula which shows a joint variation are

II.V=πr^2h and III. V=Bh

Answer is C. II and III only
