Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(83.9855/π) = 5.1704 inches
d = 2 × 5.1704 = 10.3409 inches
Instant diameter calculation and visualization
r = √(83.9855/π) = 5.1704 inches
d = 2 × 5.1704 = 10.3409 inches
