Question

Radii of two cones is equal if their slant height ratio is 5:4 find the ratio of their curved surface area

Answer 1

Heya !!

Here's your answer.. ⬇⬇
____________________

Radius of cone1 = Radius of cone2

slant Height of cone1 = 5x
slant Height of cone2 = 4x

C.S.A of Cone1 = C.S.A of cone2
πrl = πrl
5x= 4x
5 = 4

Ratio of their C.S.A is 5:4.

Answer 2

Answer :-

Radius of cone1 = Radius of cone2

slant Height of cone1 = 5x

slant Height of cone2 = 4x

C.S.A of Cone1 = C.S.A of cone2

πrl = πrl

5x= 4x

5 = 4

Ratio of their C.S.A is 5:4.
