A cone-shaped container on a farm is used for storing animal feed. The container has a radius of 4 feet and a height of 12 feet. What volume of feed, in cubic feet, can the container store? Round your answer to the nearest hundredth. Use 3.14 for π

To find the volume of a cone-shaped container, you can use the formula:

\[ V = \frac{1}{3} \pi r^2 h \]

where:

  • \( V \) is the volume
  • \( r \) is the radius of the base of the cone
  • \( h \) is the height of the cone
  • \( \pi \) is approximately 3.14

In this case, the radius \( r \) is 4 feet and the height \( h \) is 12 feet.

Now, plug in the values:

\[ V = \frac{1}{3} \times 3.14 \times (4)^2 \times 12 \]

Calculate \( (4)^2 \):

\[ (4)^2 = 16 \]

Next, substitute that back into the volume formula:

\[ V = \frac{1}{3} \times 3.14 \times 16 \times 12 \]

Now, multiply \( 16 \) and \( 12 \):

\[ 16 \times 12 = 192 \]

Now, continue with the volume calculation:

\[ V = \frac{1}{3} \times 3.14 \times 192 \]

Next, compute \( 3.14 \times 192 \):

\[ 3.14 \times 192 = 602.88 \]

Now, divide that by 3:

\[ V = \frac{602.88}{3} = 200.96 \]

Thus, the volume of the cone-shaped container is approximately:

\[ \boxed{200.96} \text{ cubic feet} \]
