How many kg does this pile of sand weigh? (1 cubic meter of sand weighs 825kg)

If the volume of the cylinder is 27 cubic decimeters, then the volume of the cylinder is (9 cubic decimeters). If the volume of the cylinder is 27 cubic decimeters, then the volume of the cylinder is (81

The area and height of the bottom of a cylinder and a cone are equal respectively, and the volume of a cone is equal to that of a cylinder______ The volume of a cylinder is the volume of a cone______ ．

The volume of a cone with equal base is 13 times that of a cylinder, and the volume of a cylinder is 3 times that of a cone

The bottom area and height of a cylinder and a cone are respectively equal. It is known that the circumference of a cylinder is 62.8 decimeters, and the height is 6 decimeters. What is the volume of a cone
1. The area and height of the bottom of a cylinder and a cone are equal respectively. The circumference of a cylinder is known to be 62.8 decimeters,
When the height is 6 decimeters, what is the volume of the cone cubic decimeters?
2. If a 40 cm high cylindrical timber is sawed along the bottom diameter, its surface area will increase by 160 square centimeters. What is the original volume of this timber?
3. The ground radius of a cone-shaped wheat pile is 2 meters and the height is 3 meters. If the pile of wheat is put into a cylindrical grain bin, it only accounts for 4 / 7 of the grain bin volume. The bottom area of the grain bin is 7 square meters. How many meters is the height of the grain bin?
Come on, come on!! Please.

1.62.8÷3.14÷2=10(dm) 10×10×3.14×6÷3=628(dm3)
2.160÷2×40=3200(cm3)
3.2×2×3.14×3÷3=12.56m3 12.56÷4/7÷7=3.14(m)

The area of the bottom of the cylinder and the cone is equal, the height of the cylinder is 2 / 3 of that of the cone, and the volume of the cone is 12 cubic decimeters

Area of cylinder bottom: area of cone bottom = 1:1
Cylinder height: cone height = 2:3
Cylinder volume: cone volume = 1 × 2:1 × 3 × 1 / 3 = 2:1
The volume of the cylinder is 12 × 2 = 24 (cubic decimeter)
