Can you help me please?

I'm not just going to give the answer, feel free to reply to this meassge to ask any more questions if you still don't understand. Also please excuse any spelling mistakes, I've done all my maths at school in Welsh so I'm translating terms in my head.

What if I say that it's given you everything you need to calculate the circumference for each pencil and the elastic band is in contact with 25% of the circumference of each pencil, you also need to remember about the straight sections of the band though. I'll leave that for you to work out.

I'm always happy to help a bit more so just send a reply or even a PM if you want if you're still stuck.
