Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(11.9588/π) = 1.9511 inches
d = 2 × 1.9511 = 3.9021 inches
Instant diameter calculation and visualization
r = √(11.9588/π) = 1.9511 inches
d = 2 × 1.9511 = 3.9021 inches
