Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(194.9169/π) = 7.8768 inches
d = 2 × 7.8768 = 15.7536 inches
Instant diameter calculation and visualization
r = √(194.9169/π) = 7.8768 inches
d = 2 × 7.8768 = 15.7536 inches
