Question

let height of a cone is equal to its diameter then its slant height ___ times to its radius[]

plz give correct answer friends​

Answer 1

Let slant height be 'l'.

Let radius of vase be 'r'

Thus, height, h = 2r

Now, we know that, l = √(r^2 + h^2)

=> l = √[r^2 + (2r)^2]

=> l = √5r^2

=> l = √5 r.

Thus, It's slant height us √5 times it's radius.
