This cylinder is 7 inches tall and has a volume of 63π cubic inches. What is the area (in square inches) of the cross section? 1.40
2.42

4.46

The answer choices are not posted, but this is how you calculate the answer.  Multiply $5.29 per yard by the total number of yards purchased.
= $5.29 per yard * 16.3 yards= $86.227

*or $86.23 rounded to the hundredths place

ANSWER: The exact answer is $86.227 for 16.3 yards.  Not knowing the answer choices, you could estimate to $86.00, you could estimate to $86.23, you could even estimate to $90.00.
Hope this helps!  :)
