## Homework Statement

find the length of the arc

x = 3y^ (4/3) - 3/32y^(2/3) and y lies between 0 and 216

## Homework Equations

l = integral sqrt (1 + (dy / dx )^2)

## The Attempt at a Solution

after integration i got this y + 3/16y ^(-4/3) / (-4/3)

i have to apply 0 and 216 is that correct i get a ridiculous answer
