Yesterday (Friday, 20th May), many GCSE students sat the Edexcel GCSE Mathematics Paper 1 (Non Calculator).
The last question has been referred to as an ‘impossible’ question by students and many teachers have taken time to have solve it. I wanted to post a reconstruction of the question here to see if anyone can solve it.
Some notes:
- No calculators allowed
- Try to complete within 5 minutes (a minute a mark)
The question is as follows:
Work out the radius of the shaded region. Leave your answer in terms of π.
AB = BC
AB = 4cm

EDIT: If you solve it, leave your answer in a spoiler!
