Science:Math Exam Resources/Courses/MATH101/April 2016/Question 08 (b)/Statement

Let $A$ be the region to the right of the $y$-axis that is bounded by the graphs of $y=x^2$ and $y=6-x$. Both parts of this question concern this region $A$.

(b) Write down an expression, using horizontal slices (disks), for the volume obtained when the region $A$ is rotated around the $y$-axis. Do not evaluate any integrals; simply write down an expression for the volume (you don’t need to justify it).
