Answer:
begin mathsize 16px style the space total space height space be space straight H
the space cone space will space be space divided space into space 2 space parts
straight a space cone space and space frustum
let space straight h space be space height space of space small space cone
straight h over straight H equals 1 half equals straight r over straight R
volume space of space frustum equals 1 third πR squared straight H minus 1 third πr squared straight h........ open square brackets 1 third πr squared straight h equals 1 third cross times 1 over 8 πR squared straight H close square brackets
equals 1 third πR squared straight H cross times 7 over 8
ratio equals fraction numerator 1 third πR squared straight H cross times 7 over 8 over denominator 1 third cross times 1 over 8 πR squared straight H end fraction equals 7 colon 1..................... left parenthesis frustum colon cone right parenthesis
end style
