Final answer:
To convert 19.4 meters to inches, multiply by 39.37 and round to three significant figures.
Step-by-step explanation:
To convert from meters to inches, we can use the conversion factor of 1 meter = 39.37 inches.
So, to convert 19.4 meters to inches, we multiply 19.4 by 39.37:
19.4 m × 39.37 in/m = 763.798 in.
However, since the original measurement is given to three significant figures (19.4), we limit our final answer to three significant figures:
763.798 in ≈ 764 in.
