Question

The diameters of two cones are equal. If their slant heights are in the ratio 5 : 4, find the ratio of their curved surfaces.

Answer 1

Answer:

Step-by-step explanation:

Given that,

Diameters of two cones are equal

Their radius are also equal i.e.,r1 = r2

Let the ratio of slant height be x

l1 = 5x and l2 = 4x
