Example - I measure the radius of a circle at 3.0 units. The circumference of that circle is therefore 3.0(pi)r, and my calculator tells me that the answer is 18.8495559215. But since my measurement was only accurate to one decimal place, the significant figure answer is 18.8.

Mathy friends, what is “Fig” in “Fig & Trig”?@tkinias Retired engineer here - and I think "figures" is likely correct. In trigonometry, it's tempting to put down the precise answer that the table or the calculator provides, even though you can't guarantee the accuracy of that number. Significant figures defines how precise of an answer you can calculate.
