When you perform any arithmetic operation, it is important to remember that the result can never be more precise than the least precise measurement.
Since there are only three significant digits past the decimal point in 7.506, and two significant digits past the decimal point in 3.14, there can only be two significant digits past the decimal point in your answer.
Thus, the correct answer would be 23.57 (with rounding).

It's 23.6! The exact answer is 23.56884. The correct number of sig. figs is 3, because 3.14 has 3 and 7.506 has 4, and when you multiply two numbers together, the answer has as many sig. figs as the less precise of the two numbers. Therefore the answer is 23.56884 rounded to three sig. figs (NOT three decimal places), and that's 23.6.

Your answer should have only 3 significant digits because in multiplication (roughly) the answer cannot have more significant digits than the fewest number in the numbers you're multiplying.

Well, how many significant digits do you want??
3.14 x 7.506 = 23.56884 (exactly)
or, are you abbreviating "pi" to 3.14 and need to use a longer string of numbers for pi? What you're asking isn't very clear.

553, so three significant figures because the number with the least sig figs has three.
