18 sf
The rounded value is 10. See also the links below. * * * * * However, there is no such thing as the correct number of significant figures (sf). SF depends on the context as well as the SF of the numbers used to compute the value.
The number has 2 significant figures.
For any arithmetic operation, the number of significant digits in the operands determines the maximum number of significant digits in te answer. There is no point in trying to calculate a highly precise answer if your operands cannot justify it. For example, if you are using pi = 3.14, (3 sf) then there is no point in measuring the radius of a circle to 7 sf and giving its area to 10 sf.

round to the first significant figure
There are 4 sf. The trailing 0s in 4.00700 must be there for a reason and that reason is that they are significant. But, if you multiply a number with 6 sf by a number with 4 sf then the answer can have at most 4 sf.
Rounding is a good idea when:one of the components in a sum is given to fewer significant figures. Often, the answer cannot contain more significant figures (sf) than the lowest sf of its components.the exact answer is irrational (or transcendental) and it is impossible not to round the answer.
0.00100 Although the two trailing zeros do not change the value of the number their presence indicates the number of sf.

The phone number of the Sf Museum And Historical Society is: 415-537-1105.
The number cannot be 64 when rounded to 1 sf.
