Rotating 2D Shapes

Front

What is the result of rotating a right trapezoid around a segment?

Back

The result is a lamp shade.

Front

Which 2D shape does not result in a rectangular prism when rotated?

Back

There is not a 2D shape that will result in a rectangular prism after a rotation.

Front

What shape is formed when a triangle is rotated around one of its sides?

Back

A cone is formed.

Front

What is the result of rotating a triangle around the y-axis?

Back

The result is a cone.

Front

What is the shape formed by rotating a rectangle around one of its sides?

Back

A rectangular prism is formed.

Front

What is the relationship between the radius and height of a cone formed by rotating a triangle?

Back

The radius is half the diameter of the base, and the height is the length of the side perpendicular to the base.

Front

What is a cylinder?

Back

A cylinder is a 3D shape with two parallel circular bases connected by a curved surface.

Front

What is the difference between a cone and a cylinder?

Back

A cone has a single circular base and tapers to a point, while a cylinder has two parallel circular bases.

Front

What happens when a circle is rotated around its diameter?

Back

It forms a sphere.

Front

What is the formula for the volume of a cone?

Back

The volume of a cone is V = (1/3)πr²h, where r is the radius and h is the height.
