वर्तुळाच्या दोन जीवा AB आणि CD वर्तुळाच्या बाहेर F बिंदूला छेदतात.
AF = 12 सेमी
BF = 4 सेमी
CF = 16 सेमी
वापरलेली संकल्पना:
जर वर्तुळाच्या दोन जीवा AB आणि CD वर्तुळाच्या बाहेर F बिंदूवर छेदल्या तर,
AF × BF = CF × DF
गणना:
DF एक सेमी मानूया
तर, संकल्पनेनुसार,
AF × BF = CF × DF
⇒ 12 × 4 = 16 × a
⇒ 48 = 16a
⇒ a = 48/16
⇒ a = 3
म्हणून, DF = 3
आता,
CD = CF - DF
⇒ CD = 16 - 3
⇒ CD = 13 सेमी
∴ CDची लांबी 13 सेमी आहे.
