I need to know whether 18 cm is the diameter or the radius. Here are both possibilities using π = 22/7:
1) If 18 cm is the diameter (so r = 9 cm):
- Area = πr^2 = (22/7) × 9^2 = (22/7) × 81 = 1782/7 cm^2 ≈ 254.57 cm^2.
2) If 18 cm is the radius (r = 18 cm):
- Area = πr^2 = (22/7) × 18^2 = (22/7) × 324 = 7128/7 cm^2 ≈ 1018.29 cm^2.
Tell me which one you meant and I’ll confirm.
