Enter that expression into a calculator. My calculator has for an answer: 1.41... E18
The E18 means that in scientific notation the answer is 1.41 x 10^18.
Although there are more digits in the answer, since 3.14 and 695000 each has only 3 significant digits, the answer should be rounded to three significant digits, also.
