The answer to your question is the third choice
Answer:
50.24 ft^2
Step-by-step explanation:
Well formula for area of a circle is pi(radius)^2
so the radius is 4 so you square that it’ll be 16
then do 16(3.14)
you’ll get 50.24
If -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)
<h3>How to determine the true statement?</h3>
The root of the polynomial function is given as:
-3 + i
The above root is a complex root.
If a polynomial has a complex root, then the conjugate of the root is also a root of the function
The conjugate of -3 + i is -3 - i
Hence, if -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)
