Question

There two counts the ratio of the radii are 4:1 also the slant height of the second cone is twice that of former find the relationship between their curved surface area​

Answer 1

Radii Ratio= 4:1 = 4x : 1x

Slant Height of Cone A=2* (Slant height of Cone

B) Curved Surface Area of Cone B = n*x*2y= 2nxy

Slant Height Raio= 1:2 = 1y : 2y

Curved Surface Area of Cone A = n*4x"y= 41xy

Ratio of Curved Surface Area: 4Txy / 2nxy

= 2:1
