C= 2*pi*r
pi= approx. 3.14
So
The first one with the radius being 18 would be approximately 113.04
BECAUSE 18 * 2 = 36
36*3.14= 113.04
DO THE SAME PROCESS with the other values you were given...

Also if they give you the diameter the formula is C= d*pi
that formula is the same as c=2*pi*r  ..... Use either... just remember when they give you the radius.... the radius is half of the diameter... so take the radius times 2 and times that by pi 
When it asked for an approximation use 3.14 for pi.
I'm sure you can do the rest by yourself. I hope this helped!

Find f(5). f(x) = x2 + 2x A)15 B)20 C)30 D)35
inysia [295]

f(5) means to replace x in the equation with 5 then solve.

f(x) = x^2 +2x

f(5) = 5^2 + 2(5)

f(5) = 25 +10

f(5) = 35

The answer is D)35

Factor completely 8x5 2x4 4x2. Prime 2(4x5 x4 2x2) 2x(4x4 x3 2x) 2x2(4x3 x2 2).
Alecsey [184]

The complete factor of the expression \rm 8x^5 + 2x^4 + 4x^2 is \rm 2x^{2} (4x^3 + x^2 + 2 )correct option is D.

<h3>What is a factorization?</h3>

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The expression is \rm 8x^5 + 2x^4 + 4x^2.

To solve the expression properly we have to take common (2x²). Then we have

\rm 8x^5 + 2x^4 + 4x^2\\\\2x^{2} (4x^3 + x^2 + 2 )

The factor is \rm 2x^{2} (4x^3 + x^2 + 2 ).

More about the factorization link is given below.
