Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिया गया है:
वृत्त की त्रिज्या = 3 सेमी
जीवा AB की लम्बाई = 2 सेमी
जीवा CD की लम्बाई = 3 सेमी
प्रयुक्त सूत्र:
कर्ण2 = लम्ब2 + आधार2
गणना:
अब △OFB से,
⇒ OF2 = 32 − 12
⇒ OF2 = 9 - 1
⇒ OF2 = 8
⇒ OF = \(2\sqrt2\)
△OEC से,
इसलिए, AB और CD के बीच की दूरी,
⇒ OE2 = 32 − \(({3\over 2})^2\)
⇒ OE2 = 9 - \(({9\over 4})\)
⇒ OE2 = \({27\over 4}\)
⇒ OE = \(3\sqrt3\over2\)
⇒ FE = OF + OE
⇒ FE = \(2\sqrt2\) + \(3\sqrt3\over2\)
⇒ FE = \(\bf \frac{{4\sqrt 2 + 3\sqrt 3 }}{2} \)
∴ दोनों जीवाओं के बीच की लम्बवत् दूरी सेमीहै।
