Thread: Using the Binomial Theory to determine the approx. percentage change in the area?

Im so stuck on this! please help!!

thank you

You are "stuck" implies that you have started the problem but then ran into a problem. Okay, what have you done and exactly where did you hit the "problem"?
If you have not done anything, perhaps the problem is with basic formulae or definitions. Do you know how to find the area of a circle? Do you know what the "binomial theorem" is?

When i said stuck i meant im working on a college assignment and came to this question. the reason im stuck on it is because our teacher hasnt gone through this with us yet. ive tried google'ing binomial theorem and i cant find anything that relates to what i need to do. is there any possibility that you could show me step by step how id work this out??

Thank you

But yes i know how to work out the area of a circle.
