Immerse a shot in a bucket with a bottom radius of 8 decimeters. The height of the water surface rises from 4 decimeters to 4.2 decimeters. What is the volume of the shot What is the volume of this shot put in cubic decimeter?

Immerse a shot in a bucket with a bottom radius of 8 decimeters. The height of the water surface rises from 4 decimeters to 4.2 decimeters. What is the volume of the shot What is the volume of this shot put in cubic decimeter?

The volume of water rising is the volume of shot put, which is 0.2 times the square of π times 8

There is a hollow shot which weighs 5.5 Newton and has a volume of 0.3 square. If the shot is immersed in water, it will (float or float or sink)

Sinking
If the shot is completely immersed in the water, the mass of boiled water is 0.5kg (the density of water is 1kg / DM ^ 3), and the buoyancy is 5N
So it's sinking

The gravity of the hollow shot is 4.9n and the volume is 6.0 × 1 - to the fourth power m3,
The buoyancy is (), buoyancy is () due to gravity, and the buoyancy and sinking of hollow shot are () (G is 10N / kg)
