The graph of the equation x +y = 52/3 is one of a family of curves called astroids because of
2/3 2/3
their starlike appearance (as shown in the accompanying figure). Find the length of this particular astroid
3/2 5√2
4
by finding the length of half the first-quadrant portion, y = (52/3-2/33/2 sxs 5, and
multiplying by 8.
The length of the given astroid is.
(Simplify your answer. Type an exact answer, using radicals as needed.)
