Pressure = Force / Area Steps:

• Radius r = circumference / (2π) = 1.4 / (2 × 3.14) ≈ 0.223 m.
• Foot area A = π r² ≈ 3.14 × (0.223)² ≈ 0.156 m².
• Force per foot = (5000 kg × 10 m/s²) / 4 = 12,500 N (using g ≈ 10 for approximation).
• Pressure P = 12,500 N / 0.156 m² ≈ 80,000 Pa ≈ 85 kPa (rounded).

Why C is correct:

• Pressure formula P = F / A gives ~85 kPa when weight is divided equally among four feet and area is calculated from the circular cross-section.

Why the others are wrong:

• A: Assumes diameter of 1.4 m, yielding unrealistically large area and low pressure.
• B: Likely miscalculates area as linear dimension, underestimating pressure.
• D: Uses total weight on one foot, ignoring distribution across four feet.

Final answer: C
