Answer:
21.2 yd
Step-by-step explanation:
8 + 6 + 7.2 = 14 + 7.2 = 21.2
9*6 = 54 which is also divisible by 2 and 3
another one would be 2*54 = 108
Answer 54 and 108.
A circle is characterized by radius, arc, sectors and circumference
- The length of the major arc is

- The radius of the circle is 15
- The area of the shaded sector is

<h3>Length of the major arc</h3>
The given parameters are:
--- the circumference
-- the center angle
The length of the major arc is calculated using:

So, we have:

Evaluate

Hence, the length of the major arc is 
<h3>The radius of the circle</h3>
The circumference is given as:

So, we have:

Divide through by 2pi

Hence, the radius of the circle is 15
<h3>The area of the shaded sector</h3>
The area of a sector is:

So, we have:

Evaluate

Hence, the area of the shaded sector is

Answer:
600 miles in a day.
Step-by-step explanation:
Variable x = number of miles
Company A: 140 + 0.80x
Company B: 80 + 0.90x
Set up an equation:
140 + 0.80x = 80 + 0.90x
Isolate variable x:
60 + 0.80x = 0.90x
60 = 0.10x
600 = x
Check your work:
140 + 0.80(600) = 80 + 0.90(600)
140 + 480 = 80 + 540
620 = 620
Correct!
