Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(3.6919/π) = 1.0841 inches
d = 2 × 1.0841 = 2.1681 inches
Instant diameter calculation and visualization
r = √(3.6919/π) = 1.0841 inches
d = 2 × 1.0841 = 2.1681 inches
