Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(199.0128/π) = 7.9591 inches
d = 2 × 7.9591 = 15.9183 inches
Instant diameter calculation and visualization
r = √(199.0128/π) = 7.9591 inches
d = 2 × 7.9591 = 15.9183 inches
