Question

What will be the number of curved edges when a sphere cut into two halves and a cone of the same radius are attached together?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is A 1

• A cone attached to a half sphere.

From the figure, we can see that there is 1 place where the curved surface of the sphere and the curved surface of the cone meet each other.

So, the total number of curved edges is 1.
