Question

What is the sum of the total number of vertices of sphere and the total number of vertices of cone?

• A. 1
• B. 0.0
• C. 2
• D. 3

Answer 1

The correct option is A 1

• The common endpoint of two or more rays or line segments is known as Vertex.

Cone has 1 Vertex as shown below.

Sphere has 0 Vertices as shown below.

$\therefore$ number of vertices of cone + number of vertices of sphere
=1+0
=1
