Answer:
The arc length, radius and the included angle are related as
r\theta=\widehat {XYZ} where \theta is in radians.
The radius r is given by
r=\frac{\widehat {XYZ} }{\theta} \\ r=\frac{10.8}{1.8} \\ r=6\;units
Correct choice is (B).
Step-by-step explanation:
C is the answer hope it helps
87.96 You need the height of the circle which is
14 because 7 is only the radius. And you put it into the equation and solve C=2πr
Nope!
Let's say there are 14 boys and 15 girls in a math class. We can use the ratio 14:15 to find out how many boys and girls would be in a class triple the size.
There are many more ways to write a ratio than part to whole. I hope I helped! :)

3 hours = 26.25
---------------------------------
Find wages for 1 hour :
---------------------------------
1 hour = 26.25 ÷ 3 = 8.75
---------------------------------
Find wages for 8 hours :
---------------------------------
8 hours = 8.75 x 8 = $70
---------------------------------
Find wages for a week :
---------------------------------
$70 x 7 = $350
---------------------------------

---------------------------------
2 hours = $15
---------------------------------
Find 1 hour :
---------------------------------
1 hour = $15 ÷ 2 = $7.50
---------------------------------
Find 8 hours :
---------------------------------
8 hours = $7.50 x 8 = $60
---------------------------------
Find 1 week :
---------------------------------
1 week = $60 x 5 = $300
---------------------------------
Define x :
---------------------------------
Let x be the number of weeks needed
---------------------------------
Construct equation :
---------------------------------
350x = 300x + 1000
---------------------------------
Solve for x :
---------------------------------
350x = 300x + 1000
---------------------------------
Take away 300x from both sides :
---------------------------------
50x = 1000
---------------------------------
Divide by 50 :
---------------------------------
x = 20
------------------------------------------------------------------
Answer: It will take 20 weeks.
