Answer: because it is curved
Step-by-step explanation:
Answer:
If a perpendicular cut is made from a point on the circumference of the base to the vertex and the cone is opened up, a sector of a circle with radius ll is produced. Since the circumference of the base of the cone is 2πr,
therefore the arc length of the sector of the circle is 2πr
