Answer:
The volume of the solid = π²
Step-by-step explanation:
As per the given data of the questions,
The diameter of each disk is
D = 2 sin(x) - 2 cos(x)
So its radius is
R = sin(x) - cos(x).
The area of each disk is
Now,
Integrate from , we get volume:
After integrate without limit we get
Now after putting the limit, we get
V = π²
Hence, the required volume of the solid = π²
