The volume of a cylinder is equal to the area of the bottom multiplied by the height______ ．

Because the volume of the cylinder can be calculated by multiplying the area of the bottom by the height, that is, v = sh, the original statement is correct

Is it right or wrong that the volume of a cuboid cube cylinder is equal to the bottom area multiplied by the height
Bar chart can not only show the number of quantity, but also show whether the change of quantity is right or wrong

1. The volume of a cuboid cube cylinder is equal to the area of the bottom multiplied by the height
2. Bar chart can not only show the quantity, but also show the change of quantity (wrong)
The reason for the mistake is that the broken line chart can not only show the quantity, but also show the change of quantity

I found that: the bottom area of the cuboid is equal to half of the cylinder (), the height of the cuboid is equal to the cylinder (), so the volume of the cylinder
=（）*（）

The bottom area of the assembled approximate cuboid is equal to the cylinder (bottom area), and the height of the cuboid is equal to the cylinder (height). Therefore, the volume of the cylinder
=Bottom area × height
What's half of it?

When deriving the volume formula of a cylinder, the cylinder is transformed into a cuboid. The bottom area of the cylinder is equal to () of the cuboid, and the height of the cylinder is equal to () of the cuboid,
The volume of a cylinder is equal to that of a cuboid

When deriving the volume formula of a cylinder, the cylinder is transformed into a cuboid. The bottom area of the cylinder is equal to that of the cuboid (bottom area), the height of the cylinder is equal to that of the cuboid (height), and the volume of the cylinder is equal to that of the cuboid (volume). The volume of the cylinder v = (п R ＾ 2H)

The area of the bottom of the cylinder and the cone is equal, the ratio of their height is 2:3, the volume sum is 1.2 cubic meters, the volume of the cylinder () and the volume of the cone ()
Write the formula

1.2 / (2 + 3 / 3) = 0.4 (M3) cone
1.2-0.4 = 0.8 (M3) cylinder

The surface area of a cylinder is 314 square centimeters. The side area of the cylinder is just equal to the sum of the areas of the two bottom circles. What is the volume of the cylinder?

Side area = 2 π RH = 157, bottom area = π R ^ 2 = 157 / 2, get the value of R, volume = π R ^ 2h, you can calculate the answer yourself

The side area of a cylinder is equal to () times (). The side area of a cylinder plus () is the surface area of the cylinder
Write it down

The side area of a cylinder is equal to the circumference of its bottom multiplied by its height

Expand the cylinder so that the side area of the cylinder equals (). The surface area of the cylinder equals () plus ()

The surface area of a cylinder is equal to (side area) plus (two bottom areas)

After cutting a cylinder 1 decimeter high into two equal half cylinders, the surface area increases by 60 square centimeters. What is the volume of this cylinder in cubic centimeters?

From the meaning of the title:
The increased surface area is the size of two rectangles;
Length = cylinder height, width = cylinder diameter
Height = 1 decimeter = 10 cm
Diameter = 60 ﹣ 2 ﹣ 10 = 3cm
Radius = 1.5 cm
volume
=3.14×1.5×1.5×10
=70.65 cm3

After a cylinder with a diameter of 10cm is cut longitudinally along the diameter, the surface area increases by 2 square centimeters. What is the original volume of the cylinder

The height is: 2 △ 2 △ 10 = 0.1cm
The radius of the bottom surface is: 10 △ 2 = 5cm
The volume is: 3.14 × 5 × 5 × 0.1 = 7.85 cubic centimeter

The volume of a cylinder is equal to the area of the bottom multiplied by the height______ ．
