दो वृत्तों की परिधि क्रमशः 110 सेमी और 330 सेमी है।
प्रयुक्त सूत्र:
वृत्त की परिधि = 2πR (R = त्रिज्या)
गणना:
माना, बड़े और छोटे वृत्तों की त्रिज्याएँ क्रमशः R और r हैं।
इनकी त्रिज्याओं के बीच का अंतर = (R - r)
अवधारणा के अनुसार,
2πR - 2πr = 330 - 110
⇒ 2π(R - r) = 220
⇒ 44/7 × (R - r) = 220
⇒ (R - r) = (220 × 7)/44
⇒ (R - r) = 35
∴ इनकी त्रिज्याओं के बीच का अंतर 35 सेमी है।
