let vertex of cone is  A ...


after drawing the axis about which cone is to cut  , then we will see that there will be two similar triangles  ...


radius of base of upper half is r1 & radius of base is R , height of original cone is 2H then


by using similarity of triangles , r1/H = R/2H


r1 = R/2     


area of upper half = 1/3 (pi) (r1)2H = 1/3(pi)(R2H/4)


area of lower half = area of cone - area of upper half


                         =1/3(pi)(R22H) - 1/3(pi)(R2H/4)


                         =1/3pi(7R2H/4)


ratio of two parts = upper half/lower half = 1/7
