Question

what is the length of an arc of central angle 60° ,in a circle of radius 3 cm​

Answer 1

Since r = 3, the full circumference is 2·π·3 = 6π units. 60° is only 60/360 = 1/6 of the way around the circle, so its arc length is 1/6 of the full circumference, or (1/6)·6π = π units.

Answer 2

Answer:

The answer is 6.284 units

Step-by-step explanation:

r=6 given. Theta = 60 degrees= 60 * pi/ 180 radians. s= 6 * 60*pi/180=2* pi= 6.284. Answer Length of the arc is 6.284 units.
