Step-by-Step Solution
- Start with the circle area formula: A = πr²
- Solve for radius: r = √(A/π)
- Calculate diameter: d = 2r
r = √(77.6214/π) = 4.9707 inches
d = 2 × 4.9707 = 9.9414 inches
Instant diameter calculation and visualization
r = √(77.6214/π) = 4.9707 inches
d = 2 × 4.9707 = 9.9414 inches
