Answer:
Step-by-step explanation:
The circumference of the outside of a ring is 66 mm and it has an outer diameter of 21 mm. The difference between the outer diameter and the inner diameter of the ring is its thickness. The thickness is constant around the ring. This means that inner outer and circles of the ring are similar. Therefore
Ratio of the outer diameter of the ring to the outer circumference of the ring = ratio of the inner diameter of the ring to the inner circumference of the ring. Therefore
21/66 = inner diameter/50
66× inner diameter = 50 × 21
Inner diameter = 1050/66 = 15.91mm
