Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(0.4025/π) = 0.3579 inches
d = 2 × 0.3579 = 0.7159 inches
Instant diameter calculation and visualization
r = √(0.4025/π) = 0.3579 inches
d = 2 × 0.3579 = 0.7159 inches
