## anonymous 5 years ago A small planet has a spherical shape, its radius is 20 km, it is covered with ice whose thickness is 1/4 km (250 m). use differentials to approximate the volume of the ice. Please show a detailed solution, @Calculus1

Dy=F'( x)(Dx) $F'(x)=4\pi r^2$ Dx=1/4 $Dy=4*\pi*20^2*.25--->1256km$ That's the volume of the Ice

2. anonymous

You have to take the derivative of the volume
