A circle with circumference 6 has an arc with a 60° central angle.

What is the length of the arc?

length of an arc = 1unit

Step-by-step explanation:

given that the circumference of a circle = 6

central angle = 60

length of the arc = ?

recall that the circumference of a circle = 2πr

6 = 2πr

r = 6/2π

now to calculate the length of an arc

recall,

length of an arc = 2πr (Ф/360)

length of an arc = 2π (6/2π) * 60/360

length of an arc = 6 * 60/360

length of an arc = 360/360

length of an arc = 1unit

therefore the length of the arc whose circumference is 6 and arc angle is 60° is evaluated to be 1unit
