A jawbreaker is a ball of hard candy filled with multiple colored layers (or rings) of hardened sugar. Mirra sells jawbreakers of three layers. The yellow core (r = 2 cm) is surrounded by a 2 cm layer of pink sugar, which in turn, is coated with 2 cm of white sugar. If each layer is 1 cm thicker than it is supposed to be, use partial differentials to approximate how much larger (in cm²) the cross sectional area will be.

A jawbreaker is a ball of hard candy filled with multiple colored layers (or rings) of hardened sugar. Mirra sells jawbreakers of three layers. The yellow core (r = 2 cm) is surrounded by a 2 cm layer of pink sugar, which in turn, is coated with 2 cm of white sugar. If each layer is 1 cm thicker than it is supposed to be, use partial differentials to approximate how much larger (in cm²) the cross sectional area will be. Divide your final answer by before inputting.
