Description

1. Calculate (up to two decimal places) the area of the figure bounded by the above lines.
1.28 x2 = 4y, y = 8 / (x2 + 4)

2. Calculate (up to two decimal places) the arc length of the line.
2.28 ρ = 4cosφ

3. Calculate (up to two decimal places) the volume of the body obtained by rotating the figure F around said axes.
3.28 F: 2y = x2, 2x + 2y - 3 = 0, Ox

4. Calculate (up to two decimal places) the surface area formed by the rotation of the arc of the curve L about said axis.
4.28 L: x = 2cos3t, y = 2sin3t, Ox
