Question

if two cones radius is equal and ratio of slant height is 5:3 then find the ratios of curved surface are of cones​

Answer 1

Explanation:

Hence theratio is 25 rato 9

hope it helps you

Answer 2

Answer:

Let the radius of the two cones be *r*

given that l1:l2 = 5:3

therefore l1/l2 = 5/3

csa of cone = πrl

 let csa of one cone be c1 and c2 of the other

therefore , c1/c2 = πrl1/πrl2

                 (cancle π and r as they are common )

we get , l1/l2

            5/3 (given in the question)

therefore the ratios of curved surface area of cones is 5:3
