एक वृत्त के केंद्र के एक ही तरफ दो समानांतर जीवाएँ AB = 28 सेमी और CD = 22 सेमी हैं।
उनके बीच की दूरी 4 सेमी है।
गणना:
माना, OE की लंबाई x है, EF = 4 सेमी
प्रश्न के अनुसार,
OA = OC
⇒ 142 + x2 = (x+4)2 + 112
⇒ 196 + x2 = x2 + 16 + 8x + 121
⇒ 8x = 59
x = 59 / 8
त्रिज्या का मान होगा:
√(142 + () 2 = 15.82 सेमी
∴ सही उत्तर विकल्प 3 है।
