Answer:
The cross section of a cylinder taken parallel to the base produces:
A circle
Explanation:
We know that when a solid i.e. a three dimensional figure is sliced with the help of a plane then the resulting cross-section so obtained is a two dimensional figure.
Also, when the slicing is done parallel to the base of a solid then the two dimensional figure obtained is similar to the base of the solid.
We know that the base of a cylinder is in the shape of a circle.
Hence, the cross-section so obtained is: Circle
