Question

A gas tank has a height of 8 feet and a width of 6 feet. What is the volume, in cubic feet, of the gas tank? Use 3.14 for pi.

1 answer

To find the volume of the gas tank, we need to determine its shape. If the gas tank is cylindrical, we will use the formula for the volume of a cylinder, which is:

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

where:

  • \( V \) is the volume,
  • \( r \) is the radius of the base,
  • \( h \) is the height of the cylinder.

From the question, we are given the height \( h = 8 \) feet. The width of the tank is 6 feet, which indicates the diameter of the base. To find the radius, we divide the diameter by 2:

\[ r = \frac{6}{2} = 3 \text{ feet} \]

Now we can substitute the values into the volume formula:

\[ V = \pi r^2 h = 3.14 \times (3)^2 \times 8 \]

Calculating \( (3)^2 \):

\[ (3)^2 = 9 \]

Now substitute back into the volume formula:

\[ V = 3.14 \times 9 \times 8 \]

Calculating \( 9 \times 8 \):

\[ 9 \times 8 = 72 \]

So now we have:

\[ V = 3.14 \times 72 \]

Calculating \( 3.14 \times 72 \):

\[ V = 226.08 \]

Thus, the volume of the gas tank is:

\[ \boxed{226.08} \text{ cubic feet} \]
