3 significant figures.
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
There are 2 significant figures in this number.
There are 4 significant figures in this number.
Science requires physical observation through measurement, which is always limited in precision hence significant figures. Mathematics, in contrast, deals with exact quantities represented by specific points on a number line, which implies infinite precision with infinite significant figures.
Infinite. "Exact numbers obtained from definitions or by counting numbers of objects can be considered to have an infinite number of significant figures."Chang, Raymond. Chemistry Volume 1. 10th. 1. 2010. 25. Print. .
Three significant figures are in this number.

"Pi" is an irrational number. No series of digits can represent its value exactly, whether written as a fraction or as a decimal. The decimal can be extended to any number of significant figures, no matter how large, and never ends.
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
