It is: 28 times 14 = 392
28
No, because 28 can only be calculated as a product in the following ways: 1 x 28 2 x 14 4 x 7 In the above cases, 28, 14 and 4 are all non-prime numbers, which means that 28 cannot be a product of 2 prime numbers alone.
2*14, 4*7, 7*4 and 14*2 (leaving out 1*28 and 28*1)
2 and 14

14 28 / \ / \ 7 2 2 14 / \ 2 7 Factors of 14: 7,2 Factors of 28: 2, 2, 7 Factors are prime numbers that are all the product of the original number. 7*2 is 14 and 2*2*7 is 28
-14 and 14, giving a product of -196.
You can use the following formula: C=2r∙3.14 Therefore C=2∙14∙3.14 Find the product of 2 and 14 which equals 28. Now C=28∙3.14 Find the product of 28 and 3.14 which equals 87.92. Therefore the circumference is 87.92ft.
The only positive integers that make a product of 154 are: 77, 2 22, 7 11, 14 None of these add up to 28. 77+2=79 22+7=29 11+14=25
