Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(120.1999/π) = 6.1855 inches
d = 2 × 6.1855 = 12.3711 inches
Instant diameter calculation and visualization
r = √(120.1999/π) = 6.1855 inches
d = 2 × 6.1855 = 12.3711 inches
