Find the differential dy of the given function. $y=4x-{\sin }^2(x)$ $dy=$ $x$ 3/4 Points] LARCALC12 3.9.036. The radius of a spherical balloon is measured as 9 inches, with a possible error of 0.02 inch. (Round your answers to two decimal places. (a) Use differentials to approximate the possible propagated error (in cubic inches) in computing the volume of the sphere. $\pm$ $x$ in ${}^3$ (b) Use differentials to approximate the possible propagated error (in square inches) in computing the surface area of the sphere. $\pm {\mathrm{in}}^2$ (c) Approximate the percent errors in parts (a) and (b). percent error of volume percent error of surface area $\%$ $\%$
