A circle has a radius of 5. An arc in this circle has a central angle of 162º.
What is the length of the arc?

The length of the arc is 14.13 meter.

Step-by-step explanation:

Given : A circle has a radius of 5. An arc in this circle has a central angle of 162º.

To find : What is the length of the arc?

Solution :

The circumference of circle is

Radius is r=5

Diameter is d=10

Circumference is

The angle is 162º.

The length of the arc is given by,

The length of the arc is

Therefore, the length of the arc is 14.13 meter.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
