9514 1404 393

Answer:

  53

Step-by-step explanation:

The area of the pool is ...

  A = πr²

  A = 3.14×(10 ft)² = 314 ft²

The number of bags of sand required is ...

  (314 ft²)/(6 ft²/bag) ≈ 52.33 bags

53 bags of sand are needed.

Translations, rotations, and reflections are rigid transformations. What can you conclude about the measures of sides and angles
attashe74 [19]

Answer:

After a translation, the measures of the sides and angles on any triangle would be the same since translation only involves changing the coordinates of the vertices of the triangle.

After a rotation, the measures of the sides and angles of a triangle would also be the same. Similar to translation, the proportion of the triangle is unchanged after a rotation.

After a reflection, the triangle's sides and angles would still be the same since reflection is a rigid transformation and the proportion of the sides and angles are not changed.

Step-by-step explanation:

Rigid transformations, i.e. translations, rotations, and reflections, preserve the side lengths and angles of any figure. Therefore, after undergoing a series of rigid transformations, the side lengths and angle measures of any triangle will be the same as the original triangle, generally speaking, in another position.
