Answer:
Step-by-step explanation:
For part a :
The circumference of the circle is given by the formula 2πr. We are given r so we double r and put it next to pi :
C = 2×π×r = 2×π×8 = 16π
For part b :
The area of a circle is given by the formula πr². We are given r so we square r and put it next to pi :
A = π×r² = π×8² = 64π
For part c :
The area of a square is given by the formula a² where a is the side length. This question requires an extra step as we don't have the length of the square. But we know that the diameter of the circle will be equal to the side of the length. The diameter of a circle is given by the formula 2r : so
D = 2r = 2×8 = 16
So the area of the square will equal :
A = 16² = 256
Hope this helped and brainliest and hearts please.

Step-by-step explanation: We are all familiar with the concept of polynomials. A polynomial is an algebraic expression involving an unknown variable and its positive integral powers.
Therefore, from this definition of a polynomial, we can conclude any algebraic polynomial consisting of more than one unknown variable will not be considered as a polynomial.
Thus, out of the given options, the following are polynomials.
Answer:
3s -4
Step-by-step explanation:
6s^2 +40s - 64
Factor out a 2
2(3s^2 +20s - 32)
Factor inside the parentheses
-4*8 =-32
3*8 -4 = 20
2 ( 3s -4 ) ( s+8 )
