Not sure why you're multiplying trade volume with their share price? It's a stupid scenario to think of, but the offer would be some combination of cash and shares they own, not newly printed shares out of the blue.
And if they did print more shares, how would it "tank their share price to 0"? It's not like a stupid acquisition would instantly vaporize a 2+ trillion market cap company overnight.
Most of this cash is in offshore accounts and Apple can't use it domestically without paying a boat load of taxes on it. Moreover Netflix's market cap at the moment is $212B and with even a conservative 30% acquisition premium Apple would have to pay $275-300B. They simply can't afford it.
Apples volume today was 52,649,132 which times share price is 188$ => 9.8 Billion.
Netflix's market cap is 212.41 billion so if Apple tried to print enough shares to cover the acquisition cost they'd tank their share price to 0.
