You can calculate the arc lenght by using this formula:
arc length = 2π*r*(A/360) , where A=angle of the arc.

So for you it would be:
arc length = 2π*4*(72/360) = 5.03

I hope that helped.

A crew will arrive in one week and begin filming a city for a movie. The mayor is desperate to clean the city streets before fil

Zigmanuir [339]

Answer:

See below in bold.

Step-by-step explanation:

You work in fractions of the city streets done per hour:

1/200 + 1/400 = 1 /x where x is the number of hours taken by 2 teams.

Multiply through by the LCM 400x:

2x + x = 400

3x = 400

x = 133.33 hours.

As there are 168 hours in a week they will have enough time.

Question<br> Find the distance between the points (-5, 8) and (-3,0).

Temka [501]

To calculate the distance between two points we use this formula:

$\boxed{ \boxed{{d \: = \: \sqrt{(x_2 \: - \: x_1)^{2} \: + \: (y_2 \: - \: y_1)^{2} } }}}$

<h3>We organize the values:</h3>

x₁ = -5
x₂ = -3
y₁ = 8
y₂ = 0

______________________

We apply the values already obtained to the formula to get the distance:

$d \: = \: \sqrt{( - 3 \: - \:( - 5))^{2} \: + \: (0 \: - \: 8)^{2} }$

$d \: = \: \sqrt{( - 3 \: - \: ( - 5))^{2} \: + \: ( - 8)^{2} }$

$d \: = \: \sqrt{( - 3 \: + \: 5) ^{2} \: + \: 64 }$

$d \: = \: \sqrt{ {2}^{2} \: + \: 64 }$

$d \: = \: \sqrt{4 \: + \: 64}$

$d \: = \: \sqrt{68}$

$d \: = \boxed{ \bold{ \: 2 \sqrt{17} \: units}}$

<h2>Answer: </h2>

$\huge{\boxed{ \bold{2 \sqrt{17} \: units }}}$
