A circle has a diameter of 22 cm. What is its circumference?
charle [14.2K]

Answer:

\boxed {\tt 69.08 \ centimeters}

Step-by-step explanation:

The circumference of a circle can be found using the following formula:

c= \pi d

where d is the diameter. We know the diameter of the circle is 22 centimeters. Substitute the value in for d.

d= 22 \ cm

c= \pi* 22 \ cm

We also know we are using 3.14 for pi. Substitute it in for pi.

c= 3.14 * 22 \ cm

Multiply.

c=69.08 \ cm

The circumference of the circle is 69.08 centimeters.

Use the graph below to determine a1 and d for the sequence. graphed sequence showing point 1, negative 10, point 2, negative 7,
Sonja [21]

Answer:

a_1=-10

d=3

Step-by-step explanation:

we know that                              

In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant, and this constant is called the common difference (d)

In this problem we have the ordered pairs

(1,-10),(2,-7),(3,-4),(4,-1),(5,2),(6,5)                      

Let                                          

a_1=-10\\a_2=-7\\a_3=-4\\a_4=-1\\a_5=2\\a_6=5

Find the difference between one term and the next

a_2-a_1=-7-(-10)=3              

a_3-a_2=-4-(-7)=3                  

a_4-a_3=-1-(-4)=3                        

a_5-a_4=2-(-1)=3                              

a_6-a_5=5-2=3                                                        

The difference between one term and the next is a constant        

This constant is the common difference                  

so                                                                                                                                  

The sequence graphed is an Arithmetic Sequence                    

therefore                                                                                    

The first term is a_1=-10                                    

The common difference is equal to d=3
