Isin’t question 19) 27.3 ( as you add the height of the cone too)

I think this is a different paper. Is this the Edexcel Igcse 9-1 paper

Didn't read the question, but the answer is 24.7

That’s what I meant
Couldn’t remember the exact numbers
Anyway thank you
When is the actual mark scheme going to release?

I can't post the answers until at least tomorrow!
