Question

Answer the following question: Mention the number of curved surface, curved edge and vertices in a cylinder.

Answer 1

Solution:

A cylinder is a 3-D shape,which has a radius (r) of top (same as radius of base),and it has a height(h).

1) Curved surface Area:
It has one curved surface area,area of which is given by = 2πrh

2) Curved Edges:2

It has two curved edges,one on the top in the shape of a circle and same as at bottom.

3) Vertices in a cylinder:0
There are no vertex in the cylinder.

if we are talking about faces than a cylinder has 3 face: curved surface,two circles

eg: Pen,pencil,rolling pin,cold drink cane

Answer 2

Cylinder has 3 surfaces.

i ) one curved surface .

ii ) Two flat surfaces ( Top and bottom )

iii ) It has two curved edges .

iv ) It doesn't has any vertices.
