Hint: We will first refer to a general inkpot. We will then look at its surfaces, both front and bottom surfaces and then, note down what kind of surfaces we get. Then, fill in the blank using those.
Complete step-by-step answer:
Let us refer to an inkpot.
We can clearly see the front from this picture. We see that it is cylindrical in shape. The front visible to us is in the form of a curved surface area of a cylinder.
Now, we will look at the bottom surface of this for more clarity.
Its bottom surface most definitely will look like as given below:-
We can clearly see that it is a circle or an ellipse which is a plane surface.
Hence, in an inkpot, we have both the plane and curved surfaces.
Hence, the answer for this question is ‘plane and curved’.
Additional Information:
A cylinder has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. It is the idealized version of a solid physical tin can having lids on top and bottom. This traditional view is still used in elementary treatments of geometry, but the advanced mathematical viewpoint has shifted to the infinite curvilinear surface and this is how a cylinder is now defined in various modern branches of geometry and topology.
Note: The students might get confused and write only one among curves or planes but remember that just before a blank you are given both in the statement itself. So, you must write about two kinds of surfaces.
Fun Fact:- Try stacking a few coins one on top of another, it will form a cylinder or certain volume now, even if you tilt the coins a bit to form some other kind of cylinder, the volume will still remain the same.
