A central angle measuring 120° intercepts an arc in a circle whose radius is 3. What is length of the arc of the circle formed by this central angle? Round the length of the arc to the nearest hundredth of unit.

6.28

Step-by-step explanation:

The length of arc which subtends an angle at the center of a circle is given by where r is the radius of circle.

______________________________

given

the central angle of arc is  120°

we will use value of as 3.14

r = 3

Length of this arc is

The length of the arc to the nearest hundredth of unit is 6.28

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
