Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(4.7179/π) = 1.2255 inches
d = 2 × 1.2255 = 2.4509 inches
Instant diameter calculation and visualization
r = √(4.7179/π) = 1.2255 inches
d = 2 × 1.2255 = 2.4509 inches
