Question

Hello it’s urgent pls give me answer of my question eighth and fifth

Answer 1

curved surface area of a cone = pi rl
 
ratio of slant height = 3:2
                               = 3x and 2x

from the formula = pi r3x
                           =pi r2x
divide
3/2
3:2 is the ratio of curved surface area

Answer 2

8.   let diameter of the cones be h
  therefore radius=r
  the curved surface area = pie r l
their ration of csa=pie r l/pie r l
                            =3x/2x=3/2
therefore the answer is 3:2
please mark my answer as brainliest.
please feel freee to ask doubts to me .............hope it helps
