Question

the curved surface area of cone is twice that of the other while the slant height of the slant height of the latter is the twice that of the former find the ration of Thier radii​

Answer 1

Answer:

we know, the curved surface area of a cone is given by, A = πrl

where r is the radius of base of cone and l is the slant height

a/c to question,

The curved surface area of one cone is twice that of others.i.e.,

or,

or, ....(1)

again, the slant height of later is twice that of former.

i.e., .....(2)

putting equation (2) in equation (1),

or, or,

hence, the ratio of their radii is 4: 1
