Dereks dinner plate has a diameter of about 9 inches. find its circumference and area.

Circumference = pi x diameter
diameter = 9
 circumference = 9pi or 9 x 3.14
area = pi x radius ^2 
radius =1/2 diameter
radius=4.5
pi x 4.5 ^2 
4.5 x 4.5 = 20.25
20.25 x 3.14 
area = 64 circumference =28

1. 3,751 * 2 = 7,502
2. 7,502 * 1 = 7,502
3. 11 * 682 = 7,502
4. 22 * 341 = 7,502
5. 31 * 242 = 7,502
6. 62 * 121 = 7,502

you can also take two negatives to make a positive:
-7,502 * -1 = 7,502
-3,751 * -2 = 7,502
-11* -682 = 7,502
and so on

to find the answer, you just figure out the factors of 7,502
