1. Calculate (up to two decimal places) the area of the figure bounded by the above lines.
1.26 xy = 6, x + y - 7 = 0

2. Calculate (up to two decimal places) the arc length of the line.
2.26 x = √3t2, y = t - t3 (loop)

3. Calculate (up to two decimal places) the volume of the body obtained by rotating the figure F around said axes.
