Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(99.1224/π) = 5.6171 inches
d = 2 × 5.6171 = 11.2342 inches
Instant diameter calculation and visualization
r = √(99.1224/π) = 5.6171 inches
d = 2 × 5.6171 = 11.2342 inches
