Question 324013: How long is a guy wire reaching from the top of a 6-foot pole to a point in the ground 4 feet from the pole. I know the exact length is sqrt52 but we are also supposed to find the approximated length to three decimal places and it is that part I can not figure out how to do. Could you please show me how to find the approximated length to three decimal points?

Turn on your calculator.

Press "5"

Press "2"

Press the "" key (if you are using the built in Windows calculator, check INV and then press the "x^2" key)

Round the result to 3 decimal places.

Go and explain to your instructor that approximating to three decimal places is the height of silliness. You should never express the result of a calculation involving measurement to greater precision than the least precise of the given measurements. Both of the given measurements in this problem were rounded to the nearest whole number, hence the result should have been rounded to the nearest whole number. Had s/he wanted you to be precise to three decimal places, the problem should have read:

How long is a guy wire reaching from the top of a 6.000-foot pole to a point in the ground 4.000 feet from the pole?
