Then the functional relationship between the volume V (cm3) of the cylinder and the circumference C (CM) of the bottom surface? 1. (p4-12) let the height h (CM) of the cylinder be a constant, then the functional relationship between the volume V (cm3) of the cylinder and the circumference C (CM) of the bottom surface?
The radius of the bottom circle is: C / 2 π
V=h*π*（c/2π）^2
Let the height h of the cylinder be a constant, and write the functional relationship between the volume V of the cylinder and the circumference C of the bottom
Relationship between bottom radius R and bottom perimeter C: 2 μ r = C. Therefore, r = C / 2 μ
Cylindrical volume formula: v = R ^ 2 * H = V * (C / 2) ^ 2 * H = C ^ 2 * H / (4)
Given that the generatrix l of the cone is 45 degrees from the bottom, and the volume of the cone is 9 NCM, find the height h and side area of the cone
High H
Bus √ 2H
Bottom radius H
1/3πh ³= 9π
h=3
Side area = H / (√ 2H) × π（√2h） ²= 9√2π
The volume of a cone is 50 cubic centimeters, and its height h is a function of the bottom area s
∵ conical volume = 1 / 3x bottom area x height = 1 / 3SH,
The analytical formula of H's function on S is: H = 150 / s

From a cone high 1 Cut a cone at 2 places. The volume of the cone is half of the original. ___ (right or wrong)
According to the problem stem analysis, we can get: the bottom diameter of the cut small cone: the bottom diameter of the original cone = 1:2. If the bottom diameter of the small cone is 1 and the height is 1, the bottom diameter of the original cone is 2 and the height is 2; So the volume of the small cone is: 13 × π × (12)2 × 1=π12； The original volume of the large cone is: 13 × π...
The functional relationship and definition domain between the surface area and the bottom radius of the conical can with volume V are obtained
Surface area = s bottom radius = R
R ^ 2 * pie * H = v
H * 2 * r * pie = s
Consolidated Sr / 2 = v
s,r,v>0
