Find the volume of a cylinder with a height of 12 inches and a diameter of 8 inches. Use 3.14 for pi. (1 point)

602.88 cubic inches

2,411.52 cubic inches

150.72 cubic inches

1,808.64 cubic inches

1 answer

To find the volume of the cylinder, we can use the formula for the volume of a cylinder:

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

where \( V \) is the volume, \( r \) is the radius, and \( h \) is the height.

  1. Calculate the radius: The diameter of the cylinder is 8 inches, so the radius \( r \) is half of the diameter:

\[ r = \frac{d}{2} = \frac{8}{2} = 4 \text{ inches} \]

  1. Use the height: The height \( h \) is given as 12 inches.

  2. Substitute the values into the volume formula:

\[ V = 3.14 \times (4^2) \times 12 \]

Calculating \( r^2 \):

\[ r^2 = 4^2 = 16 \]

Now, substitute this back into the volume formula:

\[ V = 3.14 \times 16 \times 12 \]

  1. Calculate:

First, calculate \( 16 \times 12 \):

\[ 16 \times 12 = 192 \]

Now, multiply this by 3.14:

\[ V = 3.14 \times 192 = 602.88 \text{ cubic inches} \]

So, the volume of the cylinder is 602.88 cubic inches.

The correct answer is:

602.88 cubic inches.
