Nếu lấy hệ quy chiếu là vòng tròn A,

Do bán kính hình tròn B gấp 3 lần bán kính hình tròn A, nên chu vi của hình tròn B cũng gấp 3 lần chu vi của hình tròn A.

Mà mỗi khi lăn được 1 vòng, hình tròn A lại đi được một quãng đường bằng  chu vi của nó.

Vậy để lăn xung quanh hình B, A phải thực hiện 3 vòng quay để quay lại điểm xuất phát.

Nhưng nếu hệ quy chiếu không nằm trên vòng A, nó đã quay được 4 vòng, vòng thứ tư là do vòng tròn B tặng thêm.

\(=61\)
