Answer:
Step-by-step explanation:
Given: AB≅DE, BC≅EF, CA≅FD
Since those are the given it is maped A to D, B to E, C to F
This is a rigid transformation because the distance is preserve (givens) and the triangle ABC is map to triangle DEF.
Rigid transformations produce congruent figures so triangle ABC is congruent to triangle DEF

Answer: 
Step-by-step explanation:
The volume of a cylinder can be calculated with the following formula:

Where "r" is the radius and "h" is the height.
The volume of a sphere can be found with this formula:

Where "r" is the radius.
Then, volume of the empty cylinder is:

And the volume of the ball is:

Finally, you need to subtract them in order to calculate how much water is in the cylinder:

156/9 = 17.3
So Lina can make about 17 beaded bracelets with 156 beads.
Hope this Helps!!
