Use differentials to estimate the maximum error in the calculated surface area.

Estimate the relative error in the calculated surface area.

please help me..thank you!

Area= 4 PI radius^2

dA= 8 PI radius dR

What is your difficulty with this?

well to be quite honest i am still not sure how to solve the two questions. i tried taking the derivative of the surface area and multiplying by .8 but this is not the correct answer.i know that the radius is is 77/2pi but could u elaborate more? thanks
