How many marks? Edexcel gcse maths paper3

Hi, there was a 5 mark question for calculating the surface area of a frustum.
(a cone was split into a smaller cone and a frustum)
I did every single thing correct EXCEPT calculate the correct radius for the small cone so my answer and all my workings used the wrong values.

How many marks do I lose because of this?

ooh i did this qs and got it right, hopefully
oof quite alot...cuz then most of ur answer is affected
u were meenna divide the length of the big one by the small one and then use that value to find the small radius (if tht makes ssnese)
u might get like 2/3 marks, depends rlly
