Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(0.4946/π) = 0.3968 inches
d = 2 × 0.3968 = 0.7936 inches
Instant diameter calculation and visualization
r = √(0.4946/π) = 0.3968 inches
d = 2 × 0.3968 = 0.7936 inches
