csa of a cone is twice the other cone if the slant height of the other cone is twice of first one then the ratio of their radius is

What is "csa"? Conical surface area?
Please also punctuate your sentences with periods and capital letters in the proper places, so we ca tell where they begin and end. 
Conic surface area = pi* (slant height)*(radius)
If cone 1 has twice the area of cone 2, and cone 2 has twice the slant height of cone 1, then cone 1 has four times the radius of cone 2.
