In a circle, chords AB and CD intersect at a point R inside the circle. If AR : RB = 1:4 and CR: RD = 4:9, then the ratio AB: CD is

Two chords AB and CD of a circle intersect at a point P inside the circle. If AB = 7cm , PC = 2 cm and AP = 4 cm, then CD is equal to: एक वृत्त की दो जीवाएं AB और CD वृत्त के भीतर बिंदु P पर एक दूसरे को काटती हैं | यदि AB = 7 सेमी, PC = 2 सेमी और AP = 4 सेमी है, तो CD किसके बराबर होगा ?

Chords AB and CD of a circle intersect at a point P inside the circle. If AB = 10 cm. AP = 4 cm and PC = 5 cm, then CD is equal to: एक वृत्त की जीवायें AB और CD वृत्त के भीतर स्थित बिंदु P पर एक दूसरे को काटती हैं | यदि AB =10 सेमी,AP = 4 सेमी और PC = 5 सेमी है, तो CD का मान क्या होगा ?

Chords AB and CD of a circle intersect at a point P inside the circle. If AB = 10 cm, AP = 4 cm and PC = 5 cm, then CD is equal to:
