Question

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

Answer 1

Solution:
Cone is a 3-D shape,shown in image attached.

it has a base radius(r), height (h) and a slant height l.

it is clear from the picture that cone has a curved surface,its bottom is a circle.

Curved surface :1

Area of curved surface = π×r×l

Curved Edge:1

perimeter of base circle is the curved edge of the cone.

Vertex :0

Cone does not have any vertex.

Hope it helps you.

Answer 2

A cone has

i ) one curved surface.

ii ) one flat ( plane ) surface.

iii ) one curved edge .

iv ) No edges.

v ) one vertex .
