What is the converted mana cost of cut // ribbons? If Demonic Dread's cascade effect revealed cut/ribbons from the library, would it be exiled or would it be cast without paying the mana cost?

Anywhere but on the stack the mana cost of a split card, and consequently derived from that the CMC, is the combined mana cost, and thus the combined CMC, of its halves. On the stack, the mana cost and CMC is calculated from the half you chose to cast. A fused spell on the stack will have the combined values once again.
Since cascade looks at the card in the library in exile, you are dealing with the combined cost. So its really hard to cascade into a split card. If you do, however, you choose which half to cast.
Edit:
Note, that cascade exiles, it does not reveal, and then looks at the exiled card to determine wether to stop or continue. when it stops you are given the opportunity to cast the last exiled card from exile.
I want to note something about how spells and abilities that involve casting a card treat split cards.
Some spells and abilities say a player may cast a spell or play a card with certain characteristics from a particular zone (examples include Electrodominance, Rishkar's Expertise, and Haakon, Stromgald Scourge, among others, but not cascade [C.R. 702.84a]). For the purposes of determining whether that player can cast a split card spell this way, what matters are the characteristics of that spell. This will in general be the characteristics of the half that player chooses (or the characteristics of both halves if the card is being cast from that player's hand and has fuse, and the player so chooses) (C.R. 601.3e; C.R. 708.3a, 702.101a). For example, with Rishkar's Expertise, that player can cast from their hand—
any half of a split card, if that half's converted mana cost is 5 or less, or
both halves of a split card, if the card has fuse and their combined converted mana cost is 5 or less.
However, in general, if the spell or ability says "You may cast target ... card..." (as in Torrential Gearhulk) or "You may cast that card..." (as in cascade [C.R. 702.84a]), that spell or ability doesn't care about the card's characteristics at the moment the card starts to be cast (for spells and abilities of the first kind, see C.R. 601.2c, 608.2b), so that if a player casts a split card this way, that player may choose either half of the card (or both halves if the card has fuse and is in the player's hand), even if the half or halves chosen don't meet the criteria called for by the spell or ability (C.R. 608.2f, 708.3a, 702.101a). For example, the sorcery half of an instant sorcery split card can be cast with Torrential Gearhulk this way (see also this thread).

Just trying to get your attention about card tags, since you've been asking a number of questions without them in the last few days and you apparently haven't noticed my first PM explaining their usage. Thank you!
