What is the arc length made by an angle of (60^\circ) in a circle of radius (10) cm?त्रिज्या (10) सेमी वाले वृत्त में (60^\circ) कोण द्वारा बने चाप की लंबाई क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( \frac{10\pi}{3} ) cm( \frac{10\pi}{3} ) सेमी
(60^\circ=\frac{\pi}{3}) and (s=10\times \frac{\pi}{3}=\frac{10\pi}{3}) cm. Convert the angle into radians before finding arc length.(60^\circ=\frac{\pi}{3}) और (s=10\times \frac{\pi}{3}=\frac{10\pi}{3}) सेमी है। चाप लंबाई से पहले कोण को रेडियन में बदलें।
