I need some help with this one... mostly on setting it up. The rest of the problems in this lesson I've done with ease, but for this one I'm confused as to how to set it up. The question reads as follows:

 

The radius of a circular disk is given as 24 centimeters with a maximum error in measurement of 0.2 centimeters.

(a) Use differentials to estimate the maximum error in the calculated area of the disk.

(b) What is the relative error? What is the percentage error?

Doing well enough @CPhill, been busy with school. Junior year of high school, still working on getting into a good college sometime in a couple of years for music performance, etc. You?

 

EDIT: Thanks for the link. For the first part at least, Example 3 from the link seems to be almost the same thing, just with different numbers. I'll try that first to see if that doesn't help at all ^^
