If a cylinder and a cone are of equal height and equal ground, the difference between their volumes is 0.16 cubic decimeter, then the volume of the cylinder is

If a cylinder and a cone are of equal height and equal ground, the difference between their volumes is 0.16 cubic decimeter, then the volume of the cylinder is

A cylinder and a cone are equal in height. Their volume ratio is 3 to 1
Their volume difference is 0.16 cubic decimeter, which is twice the volume of a cone
Cone volume = 0.08 cubic decimeter
The volume of the cylinder is 0.24 cubic decimeter

What is the volume of the original cylinder when you cut the cylinder into the largest cone and just cut off 18 cubic decimeters?

The combination of music,
The volume cut off is 2 / 3 of the volume of the cylinder, because the cone accounts for 1 / 3
The volume of cylinder is: 18 (1-1 / 3) = 27 (cubic decimeter)

The volume of a cylinder is 84 or 78 cubic decimeters. Its side area is equal to the sum of the two ground areas. What is the surface area of the cylinder?

V (volume) = π (R ^ 2) * h
S base = π (R ^ 2)
S side = 2 π RH
Because s side = 2S bottom
SO 2 π RH = 2 * π (R ^ 2)
It is concluded that h = R
Because V (volume) = π (R ^ 2) * H = 84.78, take π = 3.14
R = 3
S table = 2S bottom + s side = 2 * π (R ^ 2) + 2 π RH = 36 π = 113.04 cubic decimeter (π = 3.14)
