That answer is almost correct. The answer to 3 decimal places is 44.827. You rounded incorrectly. If you are asked for an answer to three decimal places you must look at four decimal places. If n decimal places are needed for an answer, you must calculate to n + 1 and then round.i replaced d with 8.2...then calculated it by simplifying, converting, cross multiplying, and dividing each side. and i ended up with 44.826
where do i go from there
