Please do 2.3 for me

2.1. Draw a triangle with vertices A(0, 1), B(2,0), C(3,4) and use integration to find its
area.
2.2. Sketch the region enclosed by y = vVI – 1, a - y = 1 and calculate its area.
2.3. Find the volume of the solid generated by revolving the region in 2.1 above about the
y-axis.
2.4. Find the volume of the solid generated by revolving the region bounded by y
Cos r, y = a+ 1 and a =
r about the r-axis.
