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

1 answer

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

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

Where:

  • \( V \) is the volume,
  • \( r \) is the radius,
  • \( h \) is the height,
  • \( \pi \) is approximately 3.14.

In this case, the radius \( r \) is 4 feet and the height \( h \) is 12 feet. Plugging the values into the formula:

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

Calculating \( 4^2 \):

\[ 4^2 = 16 \]

Now substitute back into the volume formula:

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

Now calculate \( 16 \times 12 \):

\[ 16 \times 12 = 192 \]

Now substitute again into the volume formula:

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

Now, calculate \( 3.14 \times 192 \):

\[ 3.14 \times 192 = 602.88 \]

Finally, we need to divide by 3:

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

Therefore, the volume of feed that the container can store is approximately:

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