What is the shape of the resulting two-dimensional cross section?
The answer is circle because if you slice a cone parallel to the base, the cross section is circle
A Right Cone is sliced parallel to its base the resulting shape is Circle.
What is cone?
A cone is a" three dimensional shape consisting one circular shape and once continuous curved surface tapering to a point".
According to the question,
A right cone is slice parallel to its base.
In order to find the resulting shape. When a right cone is sliced parallel to its base it results Circle.
Hence, right Cone is sliced parallel to its base the resulting shape is Circle.
