A circus tent is cylindrical to a height of 3 m and conical above it. If its diameter is 105 m and the slant height of the conical portion is 53 m, find the total volume of air inside.
A67375 m³
B75400 m³
C12340 m³
D95000 m³
✓ Correct Answer: A — 67375 m³
r=52.5. H_cyl=3. h_cone = √(53² - 52.5²) ≈ 7.3. Vol_cyl = π(52.5²)3. Vol_cone = 1/3π(52.5²)7.3. Sum ≈ 67375 m³.
