Actually, hoods don't "HAVE" to be petal shaped for a zoom. But if they
weren't, the lens designers would have to design a hood that was optimized
only for the wide-angle setting of the lens. Any telephoto-designed hood
would vignette at the wide-angle setting. So they opt for a compromise.

They have to be petals for zooms.
Every little bit of shade helps, especially with zooms.
Besides, they're sexy.
