The diameter is 1 cm. What is the circumference?

π

Step-by-step explanation: Because the diameter of the circle is 1cm

which means the radius of the circle is 0.5cm. After that, we'll find the

area of the circle the formula to find the area is

r (radius) = 0.5cm

So the answer will be

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.
