For a circle with a radius of 15 cm, what is the length of an arc intercepted by an angle measuring 120°?

31.43 cm

Step-by-step explanation:

The length of an arc  is calculated using the formula:

X 2r

where : theta is the angle in degree

r = radius

If the angle is given in Radian , the length can be calculated using the formula:

L = r∅

Since , the angle is given in degree , we will use the first formula.

L = X 2r

L = X 2 X π X 15

L = X 2 X X 15

L =

L = 31.42857143

L ≈ 31.43 cm

no he doesnt because "-16' is negatiive

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
