QR is sum of radii of the circle and the semicircle, 3r + 2 + 6r + 1 = 9r + 3
OR is the radii of the big semicircle minus the radii of the small semicircle, 12r + 2 - (3r + 2) = 9r
Then use Pythagoras theorem to form an equation
I don’t have access to writing materials at the moment so I can only give you the guidelines for now.

Part d (continued from the previous post)
I assume you have learnt how to find the area of sectors and the concept of radian form for angles. Let me know if you have not done so yet or if you do not understand any of my workings.
