C=2pir
20pi=2pir
20pi/2pi=2pir/2pi
R=10
Height=10/2=5
Two circles surface areas is
2*pir^2
2pi10^2
2*100pi
200pi
The cylindrical part is
2pirh
2pi*10*5
100pi
Add 100pi+200pi=300pi
Ok soo
-5x+x/2=9
- 4x/2=9
-(2^2-1 *x)=9
2x/2=- 9/2
x=- 9/2
x= -4 1/2
Reduce each ratio to its minimum expression to find if they are equal.
35:28

10:8

Since both ratios reduce to 5:4, they are equivalent.
Another way to check a:b is equivalent to c:d, is that a*d = b*c
In this case, this will be true if 35 times 8 is equal to 10 times 28:

Since both products are equal, then the ratios are equivalent.

Answer:
Quartic
Step-by-step explanation:
Given

Required
Name the polynomial
The question required that the polynomial be named based on its degree.
This implies that, we name the polynomial based on the highest power of x
Highest power of x = 4
When the highest power of x in a polynomial is 4, such polynomial is a quartic polynomial.
Hence, by degree; the polynomial is quartic
