Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
18 सेमी व 8 सेमी त्रिज्या असलेली दोन वर्तुळे बाहेरून स्पर्श करतात
वापरलेली संकल्पना:
R1 आणि R2 त्रिज्याच्या दोन वर्तुळांनी बाहेरून स्पर्श केल्यास त्यांची थेट समान स्पर्शरेषा = 2√(R1 आणि R2)
गणना:
R1 = 18 सेमी
R2 = 8 सेमी
म्हणून, थेट समान स्पर्शरेषा = 2√(18 × 8)
⇒ 2√144
⇒ 2 × 12
⇒ 24 सेमी
∴ थेट समान स्पर्शरेषाची लांबी 24 सेमी आहे.
