If a plane parallel to the ground of the cone divides the cone into two equal segments, then the ratio of the side area of the two parts is I did a good job Can you do me a favor
The ratio of the height of the separated small cone to that of the large cone is 1:2. The ratio of the side generatrix is also 1:2. The side area is proportional to the square of the generatrix. The ratio of the side area of the separated small cone to that of the large cone is 1:4. The ratio of the side area of the separated two parts is 1:3
