Paper water cups in the shape of a cone have a radius of 7 centimeters and a height of 12 centimeters. Cups come in packs of 12. What volume of water will pack of 12 cups hold? Use 3.14 for pi.(1 point) Responses 7,385.28 cubic centimeters 7,385.28 cubic centimeters 615.44 cubic centimeters 615.44 cubic centimeters 1,055.04 cubic centimeters 1,055.04 cubic centimeters 12,660.48 cubic centimeters

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

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

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

Given:

  • Radius \( r = 7 \) cm
  • Height \( h = 12 \) cm
  • Using \( \pi \approx 3.14 \)

Now we can plug in the values into the volume formula:

\[ V = \frac{1}{3} \times 3.14 \times (7^2) \times 12 \]

Calculating \( r^2 \):

\[ 7^2 = 49 \]

Now plug this value back into the volume formula:

\[ V = \frac{1}{3} \times 3.14 \times 49 \times 12 \]

Calculating \( 49 \times 12 \):

\[ 49 \times 12 = 588 \]

Now substitute this value into the formula:

\[ V = \frac{1}{3} \times 3.14 \times 588 \]

Calculating \( 3.14 \times 588 \):

\[ 3.14 \times 588 = 1847.92 \]

Now, calculate \( \frac{1}{3} \times 1847.92 \):

\[ V \approx 616.64 \text{ cubic centimeters} \]

This is the volume of one cup. To find the volume of a pack of 12 cups, multiply the volume of one cup by 12:

\[ \text{Total Volume} = 616.64 \times 12 \approx 7399.68 \text{ cubic centimeters} \]

Rounding this value gives approximately 7,400 cubic centimeters.

Based on the options provided, it seems there might have been a small rounding issue, but the closest response to our computed total volume of 7399.68 cubic centimeters is 7,385.28 cubic centimeters.

Thus, the volume that a pack of 12 cups will hold is approximately 7,385.28 cubic centimeters.
