The two numbers mentioned in the question have four significant figures (often called significant digits). If you wish to check your knowledge of sig-digs, check out the following link: http://science.widener.edu/svb/tutorial/sigfigures.html
4 significant figures.
There are 3 significant figures in 94.2.

4 significant figures.
there is one significant figure in 001 because 0's only count as significant figures when they are after a whole number and there is a decimal point. ex. there are three sig figs in 100. 1.00 and 10.0
15 000 894 written with 5 significant figures is 15 001 000, as the 894 rounds up to the nearest significant figure. 1.5001*10^7
001 has one significant digit, so the answer can only have one. 1.2 x 001 = 1
There is one significant figure in the number .001. Leading zeroes, which only serve to indicate the position of the decimal, are never significant.
