1) The width of the ring x will be equal to the difference between the larger and smaller radii: x = R – r.
2) We express the radii from the formula for the circumference: L = 2πR and l = 2πr, which means: R = L / 2π = (33π / 2π) cm = 16.5 cm. R = l / 2π = (27π / 2π) cm = 13.5 cm.
3) Then: x = 16.5 cm – 13.5 cm = 3 cm.
ANSWER: 3 cm.
