Find the length of the arc.<br> A. 15π mi<br> B. 5400π mi<br> C. 135π mi<br> D. 125π16 mi
weqwewe [10]

Answer:

A. 15π mi

Step-by-step explanation:

First find the circumference

C = 2*pi*r

C = 2 * pi*18

C = 36pi

The arc is 150 degrees

The fraction of the circle is

150/360 = 5/12

Multiply this by the circumference

5/12 * 36 pi

15 pi

17cm per minute = meters per hour
Arlecino [84]
Answer:  10.2 meters per hour; or, write as: 10 ⅕ meters per hour.
___________________________________________
Explanation:
_____________________________________
Note: "h" = time in "hour(s)" ; 
         "cm" = length in "centimeter(s)" ;
         "min" = time in "minute(s)";
            "m" = length in "meter(s)"
_____________________________________
Note these EXACT conversions:
_________________________________
100 cm = 1 m ; 
   60 min = 1 h ;
_________________________________
To solve: 

Given: 17 cm / min ; convert to:  ________ m / h 
__________________________________________________
(17 cm / min)* (1 m /100cm) * (60 min / 1 h)  = _______ m / h
__________________________________________________
The "cm" units cancel to "1"; the "min" units cancel to "1" and we are left with units of "m/h" {"meters per hour"}.
___________________________________
We are left with (17 *1 m * 60) / (100 * 1 h) =  [(17 * 60) m] / [100 h] 
                                                                 =  [(17 *60) / 100 ] meters per hour.
________________________________________________________
To simply: (17 * 60) / 100 ;
_________________________
Method 1):  To simplify: (17 * 60) / 100 ;

→Rewrite as: (17*60) / 100 = (17*20*3)/(20*5) ;  
→Cancel out the "20's "; and rewrite as: 

→ (17*60) / 100 = (17*3)/5 = 51/5 
                           = 10.2 meters per hour; or, write as: 10 ⅕ meters per hour.
________________________________________________________
Method 2) To simplify: (17 * 60) / 100 ; Use calculator (or by hand):
___________________________________
→ (17 * 60) / 100 = 1,020 /100 
                             = 10.2 meters per hour; or, write as: 10 ⅕ meters per hour.
__________________________________
Method 3) To simplify: (17 * 60) / 100 ;
_____________________________________
→ (17 * 60) / 100 = ? ;  

→ Divide BOTH the "100" AND the "60" by "10";

        → 60÷10 = 6 ; 100÷10 =10; and rewrite—replace the "60" with a "6"; and replace the "100" with a "10" ;
____________________________
→ (17*60)/100 = (17*6)/10 = 102/10

                         = 10.2 meters per hours; or, write as: 10 ⅕ meters per hour.
