What is the approximate length of arc s on the circle below? use 3.14 for pi. round your answer to the nearest tenth. 5.8 ft 6.3 ft 27.5 ft 69.1 ft

arc length = 68.1ft

Step-by-step explanation:

According to the attached picture below we can solve it as:

We have given:

central angle = 330°

r = 12 ft

pi = 3.14

To find the length of arc s on the circle we use:

central angle/360° = arc length/2πr

Substitute the values:

330°/360° = arc length(s)/2*3.14*12

arc length = 360°*2*3.14*12/330°

arc length = 69.08ft

Round off to the nearest tenth:

arc length = 68.1ft ....

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
