Why the multiple of any number other than 1 are not prime numbers

1 answer:

6 0

Because the fact that they can be the answer of a multiplication of a set of numbers other than one, means that they cannot be prime.

What is a prime number? A prime number is a number whose only factors are 1 and itself.

So for example, if you can use 2 multiplied 7 to get 14, then that means 2&7 are factors of 14. Since 14 has factors other than one and itself, then it isn't prime.

How do you find the radius of a circle with a circumference of 12pi

sergejj [24]

Answer:

Step-by-step explanation:

The circumference of a circle is $2\pir$ $\pi r$ , so $12\pi=2\pi r\\12=2r\\r=6$ . We can use this because the area of a circle is $\pi r^2$ . Thus, $\pi*6^2=36\pi$ .
