Area of a circle is:
A = (3.14)r^2
The picture shown is that the radius is 4
So,
A = (3.14)4^2
A = 50.2

Idk, I think 8.5 bc 12 is half of 24, and half of 17 is 8.5. I tried lol
Answer:
f(x) =
is the required polynomial.
Step-by-step explanation:
Given the zeroes (roots) of the polynomial are
and
.
We know that complex roots occur in conjugate pairs.
So, this means that
and
would also be the roots of the polynomial.
If
are to be the roots of the polynomial then the polynomial should have been:
.
Now, to determine the polynomial for which
would be the roots.
Roots of the polynomial are nothing but the values of x (any variable) that would make the polynomial zero.
⇒ 
⇒ 
The required polynomial would be the product of all the above polynomials.

Multiply this to get the required equation.
⇒

∴ The required polynomial is x⁴ - 2x³ + 49x² - 18x + 360 = 0.
Answer: The numbers on a distance of 3.2 units from −4 on a number line are -7.2 and - 0.8 .
Step-by-step explanation:
The numbers on a number line are from - infinity to + infinity whose center is at 0.Om left sides of 0 , there are negative integers and on the right side there are positive integers.
So, The numbers on a distance of 3.2 units from −4 on a number line are
-4 - 3.2 and -4+3.2
= - (4+3.2) and - (4-3.2)
= -7.2 and - 0.8
Hence, the numbers on a distance of 3.2 units from −4 on a number line are -7.2 and - 0.8 .
