Final answer:
To calculate the cross-sectional area of a cylinder, use the formula A = πr². The area for a cylinder with a radius of 3.25 meters is 33.2 square meters when rounded to appropriate significant figures.
Step-by-step explanation:
The question asks to find the cross-sectional area of a cylinder based on the given radius. The formula for calculating the area of a circle, which is the shape of the cross-section of a cylinder, is A = πr², where A is the area and r is the radius. The cylinder in question has a radius of 3.25 meters. Using the formula, the cross-sectional area is:
A = π × (3.25 m)² = 3.1415927 × 3.25 m × 3.25 m = 33.1831 m²
After rounding to appropriate significant figures, we get A = 33.2 m².
