Round off the following numbers to three significant figures: (a) 58 342 m, (b) 68.534 s, (c) 2553 N, and (d) 7555 kg.
(a)
To Round off:
The number 58342 m to three significant figures.
Answer to Problem 1P
The round off for number 58342 m to three significant figure is
Explanation of Solution
Given:
The given value is
Explanation:
A significant figure is defined as a method that is used to indicate an uncertainty in experimental or calculated values. Significant figures are the vital digits that are identified with certainty. Certainty is indicated first in a number followed by uncertainty.
For example: If a result is 12.3 m, 12 is certain and 3 is uncertain.
Round off the number to three significant figures.
Write the three significant figures formula.
Conclusion:
Round off the number 58342 m to three significant figures.
Thus, the round off for number 58342 m to three significant figures is
(b)
To Round off:
The number 68.534 s to three significant figures.
