💡 Analysis & Explanation
Parameter Aggregation ▼
Identify the core spatial parameters provided in the prompt: The radius (r) is strictly 7, and the height (h) is 10.
Formula Alignment ▼
The geometric volume of a solid uniform cylinder is universally defined by the equation Volume = π * r² * h.
Data Integration ▼
Inject the specific values, including the mandated fractional value for pi. Volume = (22/7) * (7)² * 10.
Sequential Calculation ▼
The square of 7 is 49. The equation becomes (22/7) * 49 * 10. The 7 in the denominator perfectly divides 49 to leave 7. This shifts the equation to 22 * 7 * 10.
Conclusion ▼
Multiplying 22 by 7 yields 154, and appending the zero from the 10 results precisely in 1540 cm³.
