An engine cylinder 15.8 cm deep is being bored such that the radius increases by 0.18 mm/min. how fast is the volume v of the cylinder changing when the diameter is 8.7 cm?

A3-dimensional figure has a square base and 4 lateral faces that meet at a point. explain the difference between the cross sections when a slice is made perpendicular to the base through the vertex, and when a slice is made perpendicular to the base and not through the vertex
