Step-by-step explanation:

So, what is radius?

Well, diameter is the distance from one side of a circle to the other.

Radius is half of diamater, or the distance from any side to the middle of the circle.

Problem #1:

In this case, the distance from side of the circle to the other side is 9.

Since this is side to side, it must be diameter. We know that radius is half of diameter, so radius is:

9/2

4.5

This is your radius.

Problem #2:

In this case, the distance from the one side to the other side of the circle is 16. Again, this is the diameter. So the radius will be half of 16:

16/2

So this is your radius.

Hope this helps!

Answer:

4.5 in. and 8 ft. respectively

Step-by-step explanation:

The diameter of a circle is the product of the radius and 2. So, the radius would be the quotient of the diameter and 2.

Let f (x) = x^2 + 3x + 2, and g (x) x - 6. Find and simplify: (f • g) (x)

Igoryamba

Answer:

(f • g) (x) = $x^{3}$ - 3 $x^{2}$ - 16x - 12

Step-by-step explanation:

(x-6)( $x^{2}$ + 3x + 2)

$x^{3}$ + 3 $x^{2}$ + 2x - 6 $x^{2}$ - 18x -12

$x^{3}$ - 3 $x^{2}$ - 16x - 12

200% of 79<br> with work plz

kiruha [24]

Well, the simplest way to do this is to do the cross-product method. First we have to have on one side x/79, and on the other side, 200/100. (Here's what it looks like when put properly) And for the cross product method, we multiply 79 by 200, which is 15800, and since we have that 100x, this is the new equation. (15800 = 100x) We divide 15800 by 100, and you get 158, So 200% of 79 is 158. I hope this helps you.
