What is the base area of the 49.5 ft diameter circular tank in square feet?

Explanation:
Base area is the area of a circle. For a circular tank, use A = πr^2. The diameter is 49.5 ft, so the radius is 24.75 ft. Squaring the radius gives 24.75^2 = 612.5625. Multiply by π: 612.5625 × 3.14159 ≈ 1,923.6 ft^2. If you prefer using diameter directly, A = (π/4) d^2 = (π/4) × (49.5)^2 = 0.785398 × 2450.25 ≈ 1,923.6 ft^2.
