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.

The volume of feed, in cubic feet, this container can store is _____.

603.19
16.76
201.06

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

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

where:

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

Given:

  • \( r = 4 \) feet,
  • \( h = 12 \) feet.

Now, substituting the values into the formula:

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

Calculating \( (4)^2 \):

\[ (4)^2 = 16 \]

Now substitute back into the equation:

\[ V = \frac{1}{3} \pi (16) (12) \]

Now calculate \( 16 \times 12 \):

\[ 16 \times 12 = 192 \]

So we have:

\[ V = \frac{1}{3} \pi (192) \]

Calculating \( \frac{192}{3} \):

\[ \frac{192}{3} = 64 \]

Thus:

\[ V = 64 \pi \]

Now, using \( \pi \approx 3.14 \):

\[ V \approx 64 \times 3.14 \approx 200.96 \]

So rounding off, we find:

\[ V \approx 201.06 \text{ cubic feet} \]

Therefore, the volume of feed this container can store is 201.06 cubic feet.
