When a rectangle is rotated in any axis or a line, the figure created by the rotation is a cylinder.
<h3>What figure will give if rectangle is rotated 360 around the y axis?</h3>A rectangle is an example of a shape with rotation symmetry. A rectangle can be rotated about its center and it will look exactly the same and be in the same location. The only difference is the location of the named points.
The shape created is a cylinder. Its height will be equal to the length of the side parallel to the axis-of-rotation. Its diameter will be equal to the length of the side perpendicular to the axis-of-rotation.
According to the question
A rectangle is rotated 360 around the y axis.
When a rectangle is rotated in any axis or a line, the figure created by the rotation is a cylinder.

Answer:
x = 4
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 1² = 9²
x² + 1 = 81 ( subtract 1 from both sides )
x² = 80 ( take square root of both sides )
x = =
=
×
= 4
