The question im trying to ask is,volume of a circular cylinder of height h and radius r is given by the equation V = πr^2h. A cylindrical tank is 15 meters tall and has a radius of 8 meters. We want to construct another cylindrical tank with a 20% volume increase but has the same radius.
Im trying to figure out how to write a script for the following: that will output and display the new height of the cylinder. Use fprintf to display the new height (by referencing a variable) of the tank to 2 decimals. Your calculation should result in a height of 18m if correct

h0 = 15;
dV = 0.2;
hf = h0*(1+dV);
fprintf('Oh my god, it''s %.2f meters tall! Aieee!',hf)
Oh my god, it's 18.00 meters tall! Aieee!

Aha thanks, I just needed a bit of assistance.
