▼

- Problem 1: Area = π * (20 cm)² = 400π cm² ≈ 1256.64 cm²; Circumference = 2 * π * 20 cm = 40π cm ≈ 125.66 cm.
- Problem 2: Area = π * (36 in)² = 1296π in² ≈ 4069.44 in²; Circumference = 2 * π * 36 in = 72π in ≈ 226.08 in.
- Problem 3: Radius = 33 in / 2 = 16.5 in; Area = π * (16.5 in)² = 272.25π in² ≈ 855.30 in²; Circumference = π * 33 in = 33π in ≈ 103.67 in.
- Problem 4: Radius = 8 cm / 2 = 4 cm; Area = π * (4 cm)² = 16π cm² ≈ 50.27 cm²; Circumference = π * 8 cm = 8π cm ≈ 25.13 cm.
- Problem 5: Area = π * (22.5 cm)² = 506.25π cm² ≈ 1590.43 cm²; Circumference = 2 * π * 22.5 cm = 45π cm ≈ 141.37 cm.
- Problem 6: Circumference = 2πr = 45 cm, so r = 45/(2π) cm; Area = π * r² = π * (45/(2π))² = 2025/(4π) cm² ≈ 161.10 cm².
