61.2^2 to 1 significant figure is 4000
Solution:
Given that
to 1 significant figure
Let us first calculate![61.2^2](/tpl/images/0437/4663/9d654.png)
Now we have to round 3745.44 to one significant figure
To round a significant figure, following steps are to be remembered:
1. look at the first non-zero digit if rounding to one significant figure
2. look at the digit after the first non-zero digit if rounding to two significant figures
3. draw a vertical line after the place value digit that is required and look at the next digit
4. If it's 5 or more, increase the previous digit by one
5. If it's 4 or less, keep the previous digit the same
6. Fill any spaces to the right of the line with zeros, stopping at the decimal point if there is one
Round 3745.44 to one significant figure:
3745.44 = 3 l 745.44 to one significant figure is 4000
[ here digit after vertical line is 7 which is greater than 5 so increase the previous digit by one and fill the spaces to the right of the line with zeros ]
So 61.2^2 to 1 significant figure is 4000
