Answer:

50.24 ft^2

Step-by-step explanation:

Well formula for area of a circle is pi(radius)^2

so the radius is 4 so you square that it’ll be 16

then do 16(3.14)

you’ll get 50.24

Determine the slope of the line that contains the given points <br><br> J(-5, -2), K(5, −4)

Irina-Kira [14]

Answer:

$-\frac15$

Step-by-step explanation:

Hello!

We can utilize the slope formula to find the slope.

Slope Formula: $S = \frac{y_2-y_1}{x_2-x_1}$

Remember that a coordinate is written in the form (x,y)

<h3>Find the Slope</h3>

$S = \frac{y_2-y_1}{x_2-x_1}$
$S = \frac{-4-(-2)}{5-(-5)}$
$S = \frac{-2}{10}$
$S = -\frac15$

The slope of the line is $-\frac15$ .

What are the slope and Y intercept of the linear function graft to the left?

Anna35 [415]

Answer:

Slope - $\\\frac{1}{2}$

Y intercept 1

so option 2 or B

Step-by-step explanation:

Slope is rise over run so 1 over -2

so -1/2

and y intercept is where the line crosses the y axis and it crosses on this graph at positive 1.

Don't guess!

Alja [10]

Answer:

The correct answer would be J; $\frac{1}{2} r + 2$ ;

Step-by-step explanation:

Using the algebra;

$\frac{1}{2} * r$ = $\frac{1}{2} r$

$\frac{1}{2} * 4 = 2$

Altogether this would give "J" as the answer.

Hope this helps!

the diameter of your bicycle wheel is 34 inches.What is its radius?How far will you move in one turn if your wheel?What is the d

gulaghasi [49]

Answer:

Step-by-step explanation:

The radius of a circle is always half the radius.

Thus, in this case, the radius is (1/2)(34 in) = 17 in.

The "how far" question is answerable by finding the circumference of the wheel. The circumference, C, is found by calculating C = πd, where d is the diameter of the circle in question.

Here, C = (34 in)π, which comes out to 106.81 inches. The bike will move 106.81 inches forward if the wheel turns once.

If the wheel turns 5 times, the total distance traveled is 5 times the circumference, or 5(106.81 in) = 534.07 in.
