Find the volume of a cylinder of height 6" and base with circumference 16 pi". A.96 pi cubic units B.192 pi cubic units C.384 pi cubic units

Respuesta :

The answer is C. 384 pi cubic units

Answer:

Option C is correct

[tex]384 \pi[/tex] cubic inches

Step-by-step explanation:

Volume of cylinder(V) is given by:

[tex]V = \pi r^2h[/tex]             ......[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=[tex]16 \pi"[/tex]

Since:

Base with Circumference(B) = [tex]2 \pi r[/tex]

[tex]16 \pi =2 \pi r[/tex]

⇒[tex]16 = 2r[/tex]

or

[tex]2r =16[/tex]

Divide both sides by 2 we have;

⇒[tex]r = 8''[/tex]

Substitute the given values in [1] we have;

[tex]V = \pi \cdot 8^2 \cdot 6 = \pi \cdot 64 \cdot 6[/tex]

Simplify:

[tex]V = 384 \pi[/tex] cubic inches

Therefore, the volume of a cylinder is, [tex]384 \pi[/tex] cubic inches
