✔ 最佳答案
Let the centre of the bigger circle be O and that of the smaller circle be Q4^2+4^2=OQ^2 (Pyth. thm.)
OQ=√32 cm
∴R=√32+4 cm
=5.67+4
=9.67cm (3 sig. sig.)

You had better use the word 'quadrant' instead of 'bigger circle' since 'quadrant' is used in the question and the 'bigger circle' is not really a complete circle.
