In circle R with m/QRS = 78 and QR= 3 units, find the length of arc QS.
Round to the nearest hundredth.


In Circle R With MQRS 78 And QR 3 Units Find The Length Of Arc QS Round To The Nearest Hundredth class=

Sagot :

Answer: 4.08 units


Step-by-step explanation: The length of an arc depends on the radius of a circle and the central angle θ. We know that for the angle equal to 360 degrees (2π), the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:L / θ = C / 2πAs circumference C = 2πr,L / θ = 2πr / 2πL / θ = rWe find out the arc length formula when multiplying this equation by θ:L = r * θHence, the arc length is equal to radius multiplied by the central angle (in radians).


Soo, 13(3.14)/10•3= 4.08 to the nearest hundredth :)

Hope it’s not to late for u :)
