Answer:

Length of Arc = 4

Step-by-step explanation:

Circumference is the whole circle's perimeter.

Arc length is a "part" of the circumference.

Whole circle is 360 degrees, so the arc length with a central angle of 72 degrees will be:

72/360 = 1/5th of the whole circle

The whole circle has circumference of "20", so 1/5 th of that would be:

(1/5) * 20 = 4

Length of Arc = 4

Find the volume of the cylinder in terms of pi.
Allushta [10]

Answer:

\large\boxed{V=81\pi\ in^3}

Step-by-step explanation:

The formula of a volume of a cylinder:

V=\pi r^2H

r - radius

H - height

We have r = 3in and H = 9in. Substitue:

V=\pi(3^2)(9)=\pi(9)(9)=81\pi\ in^3

WHATS THE SLOPE <br> FAST CORRECT ANSWER = Thanks + Brainliest + 5 stars + 8 points
umka2103 [35]

Answer:

The slope of g(x) is: m=0

The slope of f(x) is: m-1

Step-by-step explanation:

For this exercise you need to know that:

1. By definition the slope of any horizontal line is zero (m=0)

2. The slope of a line can be calculated using the following formula:

m=\frac{y_2-y_1}{x_2-x_1}

In this case, you can observe in the graph of the function g(x) given in the exercise that it is an horizontal line.  Then, based on the explanation given before, you can conclude that its slope is:

m=0

To find the slope of the function f(x) shown in the table attached, you need to follow these steps:

- Choose two points  from the table:

(0,3) and (4,-1)

- You can say that:

y_2=-1\\y_1=3\\\\x_2=4\\x_1=0

- Substitute values into the formula m=\frac{y_2-y_1}{x_2-x_1}:

m=\frac{-1-3}{4-0}

- Finally, evaluating, you get:

m=\frac{-4}{4}\\\\m=-1
