A Hemisphere-Shaped Dome of Radius 40 Ft Is to Be

Question 74

Short Answer

A hemisphere-shaped dome of radius 40 ft is to be coated with a layer of rust-proofer before painting. Use differentials to estimate the amount of rust-proofer needed if the coat is to be 0.01 in. thick.
Round the result to the nearest hundredth, if necessary.
