Answer:

61.2%

Step-by-step explanation:

Let's start by finding the total area of the circle

it says that the radius is 4 so the total area is 16π

Then let's find the area of the traingle

The hieght is 6.5 and the base is 6

.5*6.5*6=19.5

Let's then find the white area

16π-19.5=30.765

Finally we just have to do (30.765/16π)= 61.2%

For y = 3x - 2x^2 +5x^3<br> show how to find the value for y, when x = 3. Show your work

Mnenie [13.5K]

$y \: = \: f(x) \: = \: 3x \: - \: 2 {x}^{2} \: + \: 5 {x}^{3}$
Here, y is a cubic function of x.
When x = 3,
$y \: = \: f(3) \: = \: 3(3) \: - \: 2 {(3)}^{2} \: + \: 5 {(3)}^{3}$
$y \: = \: 9 \: - \: 18 \: + \: 135$
$y \: = \: f(3) \: = \: 126$
Hence, when x = 3, y = 126.
