If the arc length is (\frac{1}{3}) of the circumference then what is the central angle in radians?यदि चाप लंबाई परिधि की (\frac{1}{3}) है तो केंद्रीय कोण रेडियन में क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\frac{2\pi}{3})(\frac{2\pi}{3})
One third of the circumference gives one third of the full angle (2\pi). Hence the central angle is (\frac{2\pi}{3}).परिधि का (\frac{1}{3}) भाग पूरे कोण (2\pi) का (\frac{1}{3}) भाग देगा। इसलिए केंद्रीय कोण (\frac{2\pi}{3}) है।
