If the area of the circle shown below is 12 m2, what is the area of the shaded sector

A

Step-by-step explanation:

A)  

Step-by-step explanation:

We are given the area of the circle = 12

The central angle and the arc length = 90°

Therefore, the shaded region is quarter circle. Which is quarter of the whole circle.

So, we can find the shaded sector area dividing 12 by 4.

Area of the shaded sector =

=

Therefore, the answer is A)  

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.
