Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(398.0291/π) = 11.256 inches
d = 2 × 11.256 = 22.5119 inches
Instant diameter calculation and visualization
r = √(398.0291/π) = 11.256 inches
d = 2 × 11.256 = 22.5119 inches
