दोन वर्तुळांचा घेर अनुक्रमे 198 सेमी आणि 352 सेमी आहे.
वापरलेली संकल्पना:
दोन वर्तुळांचा घेर = 2πr
कुठे, r = त्रिज्या
गणना:
दोन वर्तुळाची त्रिज्या r 1 आणि r 2 आहे
प्रश्नानुसार,
2πr 2 - 2πr 1 = 352 - 198
⇒ 2π(r 2 - r 1 ) = 154
⇒ π(r 2 - r 1 ) = 77
⇒ आर २ - r 1 = 77 × 7/22
⇒ आर 2 - r 1 = 49/2
⇒ आर 2 - r 1 = 24.5
∴ आवश्यक उत्तर 24.5 सेमी आहे
