Question

AOB is a sector of circle is folded to form a cone. find the radius OA-
1)height of poll
2)slant height of the poll
3)half of the circumference of the base
4)circumference of the poll

Answer 1

OA is slant height of the poll....

Answer 2

The correct option is 2) Slant height of the poll.

Step-by-step explanation:

• AOB is a sector of circle is folded to form a cone.

• radius OA = slant height of cone
• To form a cone, we begin with a sector of central angle and radius s, then unite points A and B, allowing point O to rise upward until OA and OB meet. The sector's radius s is equal to the cone's slant height s.
