k The electrical resistance R of a certain wire is given by R = where k is a constant and r is the radius of the wire. Assuming that the radius r has a possible percentage error of ±4%, use differentials to estimate the percentage error in R. (Assume k is exact.) Enter the exact answer. Error = ± i % 72'
