A square prism and a cylinder have the same height. The area of the cross-section of the square prism is 628 square units, and the area of the cross-section of the cylinder is [tex]$200 \pi$[/tex] square units. Based on this information, which argument can be made?

A. The volume of the square prism is [tex]$\frac{1}{3}$[/tex] the volume of the cylinder.
B. The volume of the square prism is half the volume of the cylinder.
C. The volume of the square prism is equal to the volume of the cylinder.
D. The volume of the square prism is twice the volume of the cylinder.



Answer :

To determine the correct argument based on the given areas of the cross-sections for the square prism and the cylinder, let's proceed with the following steps:

1. Identify Given Values:
- The area of the cross-section of the square prism, [tex]\(A_{\text{square prism}} = 628\)[/tex] square units.
- The area of the cross-section of the cylinder, [tex]\(A_{\text{cylinder}} = 200\pi\)[/tex] square units.

2. Explain the Relationship:
- Since the height [tex]\(h\)[/tex] of the square prism and the cylinder is the same, the volumes are directly proportional to the areas of their cross-sections. Thus:
[tex]\[ \frac{\text{Volume of Square Prism}}{\text{Volume of Cylinder}} = \frac{A_{\text{square prism}}}{A_{\text{cylinder}}} \][/tex]

3. Calculate the Ratio:
- Compute the ratio of the areas:
[tex]\[ \text{Ratio} = \frac{A_{\text{square prism}}}{A_{\text{cylinder}}} = \frac{628}{200\pi} \][/tex]

4. Approximate the Ratio:
- Recall the approximate value of [tex]\(\pi \approx 3.14159\)[/tex], so:
[tex]\[ 200\pi \approx 200 \times 3.14159 = 628.318 \][/tex]

- Thus:
[tex]\[ \text{Ratio} = \frac{628}{628.318} \approx 0.99949 \][/tex]

5. Comparison with Options:
- The calculated ratio is approximately [tex]\(0.99949\)[/tex].
- Let's compare this ratio with each given option:
1. The volume of the square prism is [tex]\(\frac{1}{3}\)[/tex] the volume of the cylinder: [tex]\( \frac{1}{3} \approx 0.3333 \)[/tex] (Not close to 0.99949)
2. The volume of the square prism is half the volume of the cylinder: [tex]\( \frac{1}{2} = 0.5 \)[/tex] (Not close to 0.99949)
3. The volume of the square prism is equal to the volume of the cylinder: [tex]\( 1 \)[/tex] (Very close to 0.99949)
4. The volume of the square prism is twice the volume of the cylinder: [tex]\( 2 \)[/tex] (Not close to 0.99949)

6. Conclusion:
- The ratio [tex]\(0.99949\)[/tex] is extremely close to [tex]\(1\)[/tex]. This suggests that the volumes of the square prism and the cylinder are nearly equal.

Given the circumstances and the closely matching value, the correct argument can be concluded as:

None of the given arguments are correct.
