If the volume of a cone is constant, the area of its bottom is inversely proportional to its height______ ．

If the volume of a cone is constant, the area of its bottom is inversely proportional to its height______ ．

The area of the bottom of a cone × height = volume × 3 (certain), is a product of a certain, the area of the bottom of a cone is inversely proportional to the height

If the height of a cylinder is fixed, its volume is in direct proportion to the area of its bottom

Yes
V=SH
So V / S = H
Therefore, the volume is proportional to the area of the bottom
Thank you for your adoption

The bottom area of a cylinder is fixed, and its height is in direct proportion to its volume______ (judge right or wrong)

Because the volume △ height = bottom area (certain), in line with the meaning of positive proportion, the bottom area of the cylinder is certain, and its height is in direct proportion to the volume
