Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(21.8545/π) = 2.6375 inches
d = 2 × 2.6375 = 5.275 inches
Instant diameter calculation and visualization
r = √(21.8545/π) = 2.6375 inches
d = 2 × 2.6375 = 5.275 inches
