The problem is not stated clearly.
A cone made of cardboard has a vertical height of 8 cm and a radius of 6 cm.
If this cone is cut along the slanted height to make a sector,
what is the central angle, in degrees, of the sector?
The side view of the cone looks like this:
We see that the slant height is 10 cm.Code:B * /:\ / : \ / : \ / : \ 10 / :8 \ / : \ / : \ A *-------*-------* C : - 6 - : - 6 - :
The circumference of the base is: .
Now we cut the cone and lay it flat.
We have a large sector of a circle of radius 10.

We have: .
