Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(69.6418/π) = 4.7083 inches
d = 2 × 4.7083 = 9.4165 inches
Instant diameter calculation and visualization
r = √(69.6418/π) = 4.7083 inches
d = 2 × 4.7083 = 9.4165 inches
