The flagpole on the roof of the Chocolate Factory is 13 cm in diameter and a perfect cylinder. If one end of a 2300-cm-long string is attached to the top of the flagpole, and wraps around the flagpole exactly 16 times before ending at the bottom of the flagpole, how tall is the flagpole? Please round to the nearest centimetre, and submit only a number.

So circumference=2*pie*r r=d/2 so =13x3.14=40.82
and the string wraps around the pole 16 times, so 16x the circumference, 40.82x16=653.12
and subtract the horizontal distance from the total length of the string to give the vertical distance 2300-653.12=1646.88cm -> rounded up to 1647

Ans:1647



feel free to criticize this I'm pretty sure my logic is sound but I only looked at the question for a min

    Well done. Thank you very much, because your math seems to check out completely.

    I love math, but TNT likes to screw with us on math questions and include abstract tripping blocks... that's the only reason I'd be wary of an answer this easy.

    haha agreed, hence why I'm a bit skeptical on it as well, I'll probably look at their anwser next week and scratch my head as to how they managed to squeeze in the quadratic formula somewhere between castle geometry and meepits



    and edited, oh darn I put in the cm in my submitted anwser:P, but if you read their page it says they look for keywords

    Tomorrow is the new LC, so I know there's no item splitting either.

    I figured since I did none of the work I'm lucky for whatever free NP I get
