Answer:

Option C is correct


384 \pi cubic inches

Explanation:

Volume of cylinder(V) is given by:


V = \pi r^2h ......[1]

where,

r is the radius of the cylinder

h is the height of the cylinder respectively.

As per the statement:

Height of the cylinder(h) = 6"

Base with circumference=
16 \pi

Since:

Base with Circumference(B) =
2 \pi r


16 \pi =2 \pi r


16 = 2r

or


2r =16

Divide both sides by 2 we have;


r = 8''

Substitute the given values in [1] we have;


V = \pi \cdot 8^2 \cdot 6 = \pi \cdot 64 \cdot 6

Simplify:


V = 384 \pi cubic inches

Therefore, the volume of a cylinder is,
384 \pi cubic inches
