Answer:
15.7 meters
Step-by-step explanation:
Applying,
s = πd∅/360°..................... Equation 1
Where s = length of the arc formed, d = diameter of the circle, ∅ = angle formed by the center of the circle, π = pie.
From the question,
Given: d = 15 meters, ∅ = 120°
Constant: π = 3.14
Substitute these values into equation 1
s = (3.14×15×120)/360
s = 15.7 meters
Hence the lenght of the arc formed is 15.7 meters
<em><u>Answer:</u></em>
The unit rate is $2.86 per hour
<u><em>Explanation:</em></u>
The units rate is amount earned in 1 hour
We are given that the rate for 3.5 hours is $10
<u>To get the unit rate, we will use cross multiplication as follows:</u>
3.5 hours ..........> $10
1 hour ..................> ??
units rate = = which is approximately $2.86 per hour
Hope this helps :)
divide 630 by 18
630/18 = 35
so unit rate would be 35 meters per second
