Answer: lower bound = 3.107

upper bound = 3.161

Step-by-step explanation:

Circumference = 213

lower bound is 212.5 (because it rounds up to 213)

upper bound is 213.4 (because it rounds down to 213)

Note: 213.5 rounds up to 214

Diameter = 68

lower bound is 67.5 (because it rounds up to 68)

upper bound is 68.4 (because it rounds down to 68)

Note: 68.5 rounds up to 69

Circumference ÷ Diameter

Lower ÷ Lower: 212.5 ÷ 67.5 = 3.148

Lower ÷ Upper: 212.5 ÷ 68.4 = 3.107 LOWER bound (smallest value)

Upper ÷ Lower: 213.4 ÷ 67.5 = 3.161 UPPER bound (largest number)

Upper ÷ Upper: 213.4 ÷ 68.4 = 3.120
