PRACTICE ANOTHER
A solid is obtained by rotating the shaded region about the specifled line. about the $y$-axis
(1)
(a) Set up an integral using the method of cylindrical shells for the volume of the solid.
\[
V=\int^{\sqrt{\pi / 2}}(\square) d x
\]
(b) Evaluate the integral to find the volume of the solid.
Answer
Final Answer: \(\boxed{\text{The question does not provide enough information to solve the problem. We need more details about the shaded region and the function to be integrated.}}\)
Step 1 ：Set up an integral using the method of cylindrical shells for the volume of the solid. The integral is represented as \(V=\int^{\sqrt{\pi / 2}}(\square) dx\).
Step 2 ：Evaluate the integral to find the volume of the solid.
Step 3 ：The question does not provide enough information to solve the problem. We need more details about the shaded region and the function to be integrated.
Step 4 ：Final Answer: \(\boxed{\text{The question does not provide enough information to solve the problem. We need more details about the shaded region and the function to be integrated.}}\)
