What is the area of a cirlcle that's 4cm ​

Mathematics

If the radius of the circle is 4 than the area would be 50.27.

If you are saying that 4 is the diameter, than divide that by 2 to get the radius which is 2. The area for this would be 12.57.

I don’t know which one you mean but hope this helps :))

Which polynomial is prime?<br> Ox+3x²-x²-3<br> Ox4-3x²-x² + 3<br> O 3x²+x-6x-2<br> O 3x²+x-6x + 3
GarryVolchara [31]

Answer:

The polynomial 3x² + x - 6x + 3  is a prime polynomial

How to determine the prime polynomial?

For a polynomial to be prime, it means that the polynomial cannot be divided into factors

From the list of options, the polynomial (D) is prime, and the proof is as follows:

We have:

3x² + x - 6x + 3

From the graph of the polynomial (see attachment), we can see that the function does not cross the x-axis.

Hence, the polynomial 3x² + x - 6x + 3  is a prime polynomial
