Answer:

64π

Step-by-step explanation:

Since the diameter of the circle is 16, the radius is half of that which is 8.

Area = πr² = 64π

Answer:

<h2> </h2><h2> 200.96 units ${}^{2}$ </h2>

Step-by-step explanation:

Radius = 8 cm

Now, finding the area of circle:

$\pi \: {r}^{2}$

Plug the values

$= 3.14 \times {8}^{2}$

Evaluate the power

$= 3.14 \times 64$

Calculate the product

$= 200.96 \: {cm}^{2}$

Hope this helps..

Best regards!!

The volume of a rectangular prism can be modeled by the expression 4x3 - 108.

balandron [24]

Answer:

4(x - 3)(x^2 + 3x + 9)

Step-by-step explanation:

4x^3 - 108 = 4(x^3 - 27), or

4(x^3 - 3^3), or

4(x - 3)(x^2 + 3x + 9)

We could choose to let 4 represent the height of the prism, x - 3 the width and x^2 + 3x + 9 the length.

Help pleaseeeeee anyoneee?

Answer:

z = -9.538546756+ 15.26486573i

Step-by-step explanation:

z = |z| cos theta + |z| i sin theta

We know |z| and theta

z = 18 cos 122 +18i sin 122

z = -9.538546756+ 15.26486573i

In the function y = -5x2 + 5 , the graph will open down, be shifted up 5 units, and it will be wider than the parent function y

masya89 [10]

We are considering the function $y=f(x)=-5 x^{2} +5$

the graph of this function is the graph of the parent function $y=g(x)= x^{2}$ after applying the following steps.

1. multiply by -1:

$-x^{2}$ is $x^{2}$ reflected with respect to the x-axis.

2. multiply by 5:

$-5x^{2}$ is $-x^{2}$ shrinked towards the y axis.

for example, consider x=1/2

$-5x^{2}=-5( \frac{1}{2} )^{2}=-5* \frac{1}{4}= \frac{-5}{4}=-1.25$

$-x^{2}=- ( \frac{1}{2} )^{2}=- \frac{1}{4}=-0.25$

now this means that $-5x^{2}$ is "lower" than $-x^{2}$ , which means there is a shrinking of the graph.

3. add 5:

$-5 x^{2} +5$ is $-5 x^{2}$ shifted 5 units up.

4.

so the graph of the function a) opens down, b) is shifted 5 units up, c) is not wider than the parent function
