<h2> ☞ANSWER☜</h2>

<h3>3D shapes</h3>
  • Cube Cuboid
  • Sphere Square-based pyramid
  • Cylinder Triangular prism
  • Pentagonal pyramid Hexagonal prism

<h2> ☞EXPLANATION☜</h2>

<em><u>A solid of revolution is a three-dimensional figure obtained by rotating a two-dimensional figure (or curve) around a straight line (called the axis) that lies in the same plane. ... Since the triangle's interior is shaded, it creates the interior of the cone, creating a solid figure.</u></em>

<em><u>Three dimensional shapes are obtained by rotating the two dimensional shapes. When a circle is rotated we get sphere; when a triangle is rotated we get cone; when rectangle or square is rotated we get cylinder</u></em>

The answer would be A.

It is reflected across the x-axis means that point E' will be at (-3, -2) and point F' would be at (-1,-2)

the length of the line would be the same regardless of anyway you translate, rotate, or reflect it. Only if you dilate it, then an object's size can change.

Hope that helps :)

Nezavi [6.7K]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete as what is required of the question is not stated.</em>

<em>However, since the question is only limited to distance, a likely question could be to calculate the distance from Bayville to Colleyville.</em>

Represent the distance from Atlanta to Colleyville with AC

Represent the distance from Atlanta to Bayville with AB

Represent the distance from Bayville to Colleyville with BC

So, we have that:

AC = 25.5\ miles

AB = 10\frac{2}{3}\ miles

The relationship between AB, AC and BC is:

AC = AB + BC

Make BC the subject of formula:

BC = AC - AB

BC = 25.5 - 10\frac{2}{3}

Convert fraction to decimal

BC = 25.5 - 10.7

BC = 14.8

<em>Hence, the distance from Bayville to Colleyville is 14.8 miles</em>
