Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(378.031/π) = 10.9695 inches
d = 2 × 10.9695 = 21.9391 inches
Instant diameter calculation and visualization
r = √(378.031/π) = 10.9695 inches
d = 2 × 10.9695 = 21.9391 inches
