Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(7.3215/π) = 1.5266 inches
d = 2 × 1.5266 = 3.0532 inches
Instant diameter calculation and visualization
r = √(7.3215/π) = 1.5266 inches
d = 2 × 1.5266 = 3.0532 inches
