1 Put a cylindrical iron block with a bottom radius of 3 cm into a cylindrical container with a diameter of 20 cm. All the iron blocks were submerged in the water, and the water level rose by 0.3 cm. What is the height of the tapered iron block?

10x 10x 3. 14x 0.3x 3/3/3/3. 14

= 100x9.42/9.42x0. 1

= 10 (cm)

In the story of a crow drinking water, the clever crow put pebbles into a cylindrical water bottle in order to drink water. If the bottom radius of this bottle is 4 cm, the water level will rise by 5 cm after putting stones in it. Can you calculate the volume of this stone?

4x4x3. 14x5

=80x3. 14

=25 1.2(cm3)
