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?

To find the volume \( V \) of a cone, you can use the formula:

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

where \( r \) is the radius and \( h \) is the height of the cone.

Given:

  • Radius \( r = 4 \) feet
  • Height \( h = 12 \) feet
  • Using \( \pi \approx 3.14 \)

Now, plug in the values:

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

Calculating \( 4^2 \):

\[ 4^2 = 16 \]

Now substitute back into the volume formula:

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

Calculating \( 16 \times 12 \):

\[ 16 \times 12 = 192 \]

Now substitute again:

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

Calculating \( 3.14 \times 192 \):

\[ 3.14 \times 192 = 603.68 \]

Now, divide by 3:

\[ V = \frac{603.68}{3} \approx 201.2266667 \]

Rounding to the nearest hundredth:

\[ V \approx 201.23 \]

Thus, the volume of feed that the container can store is approximately 201.23 cubic feet.
