Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(15.4841/π) = 2.2201 inches
d = 2 × 2.2201 = 4.4402 inches
Instant diameter calculation and visualization
r = √(15.4841/π) = 2.2201 inches
d = 2 × 2.2201 = 4.4402 inches
