The base area of the cone is fixed, and the volume and height of the cone are in direct proportion______ (judge right or wrong)
Because the volume of the cone = 13 bottom area × height, so the volume of the cone △ height = 13 bottom area (certain), the ratio is certain, in line with the meaning of positive proportion, so the bottom area of the cone is certain, and the volume and height of the cone are in positive proportion
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
The volume of a cone is fixed. What's the ratio between the bottom area and the height
Inverse ratio
V=(1/3)sh
When V is constant, H decreases with the increase of S
So it's inversely proportional
