How long is the arc intercepted by central angle of pi over 2 rad in a circle with radius of 4.5 cm round your answer to the nearest 10th use 3.14 for pie

Step-by-step explanation:

The formula for determining the length of an arc is expressed as

Length of arc = θ/360 × 2πr

Where

θ represents the central angle.

r represents the radius of the circle.

π is a constant whose value is 3.14

From the information given,

Radius, r = 4.5 cm

180 degrees = π radians

1 radian = 180/π

2 radians = 2 × 180/π = 360/π degrees

Therefore,

Length of arc = (360/π) /360 × 2 × π × 4.5

Length of arc = 9 cm

people went from manufacturing one object at a time by hand to manufacturing many objects in factories

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
