11. 9.424 inches

Step-by-step explanation:

Problems 1-3:

S=r*Ф

S= arc length, r= radius, Ф= angle in radians

You need to convert the angle from degrees to radians before you can use it in the equation. You do this by multiplying it by pi and dividing by 180. Then you can plug this and the radius into the equation to solve for the arc length.

1) 120° x = 2.094 rad

S= 4 x 2.094 = 8.378

2) 135° x = 2.356 rad

S= 1.5 x 2.356 = 3.534

3) 240° x = 4.189 rad

S= 3 x 4.189 = 12.566

Problems 4-6:

4) 15° x = 0.262 rad or

5) 70° x = 1.222 rad or

6) 300° x = 5.236 rad or

Problems 7-9:

7) 240°

8) 165°

9) 22.5°

Problem 10:

30° = radians

45° = radians

radians = 60°

radians = 90°

120° = radians

radians = 45°

radians = 180°

radians = 270°

360° = radians

Problem 11:

S= r * Ф

S= 4 *

S= 3 = 9.424 inches

24: 56

step-by-step explanation:

24 can be divided into 3 and 56 can be divided into 7, where as all the other ratios can't.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
