The circumference of a particular circle is 18 cm. in square centimeters, what is the area of the circle? express your answer as a common fraction in terms of pi.

or

Step-by-step explanation:

Since the the formula for the circumference of a circle is and C is 18, we can substitute and solve for r. After we solve for r, we substitute it into the area formula.

The formula for the area is

As a fraction, we would not simplify to a decimal and the solution would be:

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
