Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(189.1215/π) = 7.7588 inches
d = 2 × 7.7588 = 15.5176 inches
Instant diameter calculation and visualization
r = √(189.1215/π) = 7.7588 inches
d = 2 × 7.7588 = 15.5176 inches
