Question

curved surface area of cone​

Answer 1

Answer:

The curved surface area of a cone, S = πrl units2.

Explanation:

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. ∴ The curved surface area of a cone, S = πrl units2.

Answer 2

Answer:

curved surface area of cone = πrl

r= radius

l= length
