1. Suppose that a piece of bubble gum has a volume of 4cm$^3$. A girls blows a bubble using this gum. Find the thickness of this bubble if the inner radius of this spherical bubble is 10cm. Use the linear approximation and notation of differentials to estimate this thickness.

Bubble gum's density is about $1 \mathrm{g} / \mathrm{cm}^{3} .$ You blow an $8-\mathrm{g}$ wad of gum into a bubble $10 \mathrm{cm}$ in diameter. What's the bubble's thickness? (Hint: Think about spreading the bubble into a flat sheet. The surface area of a sphere is $4 \pi r^{2} .$ )
The volume of a sphere of radius r is V = (4/3)πr^3. Write a differential formula that estimates the change in volume of a sphere when the radius changes from r0 to r0 + dr. Enter r0 as r0 and dr as dr. dV = Write a differential formula that estimates the change in volume of a sphere when the radius changes from 10 to 10 + dr. dV = Use a differential to estimate the change in volume of a melting spherical snowball when the radius changes from 10 cm to 9.6 cm. dV =
