There is a cylindrical bucket with a diameter of 8 cm. There is 15 cm deep water in the shengnuguo bucket, which just takes up more than the volume of the bucket milliliter
Diameter 8 cm radius 4 cm
Area = 3.14x4 = 50.26
Volume = 50.26x15 = 753.9ml
In a cylindrical bucket, put a section of cylindrical billet with a diameter of 12 cm into the water, and the water surface rises by 8 cm. Pull the billet out of the water vertically for 6 cm, and the water surface drops by 3 cm. Calculate the volume of the billet
Please indicate your thoughts,
From the meaning of the title:
Column height: 6 = 8:3
Namely:
Column height = 6 × 8 △ 3 = 16 cm
So:
Cylinder volume
=3.14×(12÷2)²×16
=1808.64 cm3
When a cylinder is cut into the largest cone, the volume of the cut part is 12 cubic decimeters, and the volume of the cut cone is? The volume of the cylinder and the volume of the cut part
The volume of the truncated part is 12 cubic decimeters, the volume of the truncated cone is (6 cubic decimeters), and the volume of the cylinder is (18 cubic decimeters)
