Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(16.3125/π) = 2.2787 inches
d = 2 × 2.2787 = 4.5574 inches
Instant diameter calculation and visualization
r = √(16.3125/π) = 2.2787 inches
d = 2 × 2.2787 = 4.5574 inches
