    (~3.14) * (1.2 ft)^2 = about 4.524 square feet 4.524 square feet * $5.40 = about $24.42

    Correct^ The way to get square feet would be the AREA of the fabric So area of a circle = \(\large \pi r^2 = 3.14 \times (1.2)^2\) And multiply that answer by the 5.4 per square foot to get to your answer :)
