Ms. White baked a 3-tier circular birthday cake with the diameters of 35 inches, 25 inches, and 15 inches.
She wants to put red decorative icing around the
outside edge of each layer of the cake. What is the
total measurement around the outside of the 3-tier
cake?

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
