Question

3- Curved surface area of cone match the coloum​

Answer 1

Answer:

Curved surface area of cone = πrl

Step-by-step explanation:

Curved surface area of cone = Sum of areas of all triangles that make up the circle from which the cone is made

Curved surface area of cone = 1/2 * sum of bases of all triangles * heights of all triangle

Curved surface area of cone = 1/2 * 2πr* l

Curved surface area of cone = πrl square units
