Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(213.7328/π) = 8.2482 inches
d = 2 × 8.2482 = 16.4965 inches
Instant diameter calculation and visualization
r = √(213.7328/π) = 8.2482 inches
d = 2 × 8.2482 = 16.4965 inches
