In sharing a bottle of coke with my two sons, Tom and Harry. Tom brought a 3cm diameter, 6cm tall cup which I filled to the brim. Harry brought a 6cm diameter, 3cm tall cup which I also filled to the brim.
Who had the most coke?
Volume of Tom's cup: Height of cup = 6cm Diameter of cup = 3cm Radius (r) = 1.5cm Volume = πr²h = π x 1.5² x 6 = 42.41cm³
Volume of Harry's cup: Height of cup = 3cm Diameter of cup = 6cm Radius (r) = 3cm Volume = πr²h = π x 3² x 3 = 84.82cm³
Not only did Harry had more coke, he had exactly twice of Tom's coke.
Answer: Harry
Moral: This question is very similar to Q55, diameter matters alot.

Pavel Durov, who shares our vision, supplied Telegram with a generous donation, so we have quite enough money for the time being. If Telegram runs out, we will introduce non-essential paid options to support the infrastructure and finance developer salaries. But making profits will never be an end-goal for Telegram.
