## Homework Statement

This is from my book.

## The Attempt at a Solution

[(v)(22/3)(pi2/3)]/v2/3pi = 22/3(v/pi)1/3

What am I doing wrong? Thanks.

EDIT: I made a mistake in copying over my attempt; fixed now.

I'm beginning to think that my book is wrong and that my attempt is correct. Can anyone confirm?
