Question

If a solid cone is placed over a solid cylinder having same base and height. What will be it curved surface area?

Answer 1

Answer:

πr(l+2h)  

Step-by-step explanation:

Total CSA= CSA of cone + CSA of cylinder

= πrl + 2πrh   (where l= √h^2 +r^2) (h and r of cylinder and cone are same)

= πr(l+2h)
