Question

please tell me the Curved Surface area of cone​

Answer 1

Answer:

The curved surface area of the cone can be given by finding the area of the sector by using the formula, Area of the sector (in terms of length of arc) = (arc length × radius)/ 2 = ((2πr) × l)/2 = πrl. ⇒ Total surface area of cone = πr2 + πrl = πr (r + l).

Hope it helps you.
