Area = πr^2 with π = 3.14.

- r = 6: A = 3.14×6^2 = 3.14×36 = 113.04 (too small)
- r = 7: A = 3.14×7^2 = 3.14×49 = 153.86 (between 135 and 155)
- r = 8: A = 3.14×8^2 = 3.14×64 = 200.96 (too large)
- r = 9: A = 3.14×9^2 = 3.14×81 = 254.34 (too large)

So the circle with radius 7 cm represents the base.
