Question
Set-up the integral in solving the volume of the solid formed by revolving the region
bounded by the curves a = 2y? and x = y² +1 about the line y = -2, using a
horizontal element.
Ov = 27 S, (2 – y) (1 + y²) dy
%3D
Ov= 2π (x) (V플-VE-1) dz
%3D
Ov = 27 f, (y + 2) (1 – y²) dy
%3D
Ov = 27 S (-æ) (VE –1-
V3) dz
Find the volume of the solid formed by revolving the region bounded by the curves
x = 0 and z = -3y² +12y – 9 around the x-axis using cylindrical shell method. (in
cu units.)
