Question

The coordinates A (0, 0), B (0, 4), C (4, 4), and D (4, 0) are graphed and connected together. What three-dimensional shape will be created when this shape is rotated about the y-axis? Provide an explanation for your answer to receive full credit.

Answer 1

The original shape is a square.  If rotated about the y-axis it will fill out the volume and shape of a cylinder with a height of 4 units and a radius of 4 units.

Answer 2

Answer:

A cylinder with height 4 units and radius 4 units

Step-by-step explanation:

Given that The coordinates A (0, 0), B (0, 4), C (4, 4), and D (4, 0) are graphed and connected together.

Since AB =BC=CD=DA we get all sides are equal

Also AB is y axis and AD is x axis, hence one angle is 90 hence all angles are 90 degrees.

Hence this is a square

When it is rotated about y axis, we gt a cylinder which has radius equal to side of the square and height also equal to the side of the square.
