Answer:
The shape of the cross-section is a square
Explanation:
Given
See attachment
Required
The shape of the cross-section
From the attachment, we can see that when the cylinder is cut vertically, the shape formed is a quadrilateral of equal opposite sides.
The dimension of the shape is: the height of the cylinder and the diameter of the base circle
From the given parameters, we have the radius and the height to be:
The diameter (d) is:
So, the dimension is:
and
Since the height and the diameter have the same lengths, then the shape is a square.
