Answer:
7
Step-by-step explanation:
The number of significant figures in the value "9245.800 m" is 7 significant figures.
- Non-zero digits are always considered significant. In this case, all the digits (9, 2, 4, 5, 8) are non-zero, so they are significant.
- Trailing zeros to the right of the decimal point in a decimal number are considered significant. In this case, the zeros after the last non-zero digit (8) are considered significant.
So the number of significant figures is 7.
