express your answer to three significant figures and include the appropriate units.
value units

Explanation:

Step1: Use inch-cm conversion factor

1 inch = 2.54 cm, so calculate $22.1 \times 2.54$
$\text{Value} = 22.1 \times 2.54 = 56.134$

Step2: Round to 3 significant figures

Round 56.134 to 3 sig figs
$\text{Value} = 56.1$

Step3: Use ft-m conversion factor

1 foot = 0.3048 m, so calculate $114 \times 0.3048$
$\text{Value} = 114 \times 0.3048 = 34.7472$

Step4: Round to 3 significant figures

Round 34.7472 to 3 sig figs
$\text{Value} = 34.7$

Answer:

Part A: 56.1 centimeters
Part B: 34.7 meters
