Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(210.0194/π) = 8.1763 inches
d = 2 × 8.1763 = 16.3525 inches
Instant diameter calculation and visualization
r = √(210.0194/π) = 8.1763 inches
d = 2 × 8.1763 = 16.3525 inches
