Homework 7 problem 3

jcastel1

I am having some trouble figuring out how to do problem 3 on HW 7.

y=\frac1{16}x^2,x=4, y=0

Find volume by rotating about the y-axis.
Any advice/Help would be appreciated.

I’m not sure if you’ve got this figured out yet but I’ll leave this here just in case.

The key clue for this problem is “rotating about the y-axis”.

Try solving y=\frac{1}{16}x^2 for x and modifying your bounds with the y values given in the graph provided.
