can anyone please help me the answer is 1:2 but I am getting it as 2:1 please say me step by step ​

Answer 1

Answer:

Let R be the radius of both the cylinder and the cone

Again let h and l respectively be the height and slant height of the cylinder and the cone

lateral surface of the cylinder =curved surface of the cone

⇒2πrh=πrl⇒2h=l

⇒ h/1=1/2

⇒h:1= 1:2
