The area of circle Z is 64Pi ft2. Circle Z is shown. Radius D has length r. R = StartRoot StartFraction Area Over pi EndFraction EndRoot What is the value of r? r = 4 ft r = 8 ft r = 16 ft r = 32 ft

r = 8 ft

Step-by-step explanation:

Area of a circle => πr²

We are told in the question that:

The area of circle Z is 64Pi ft²

= 64π ft²

What is the value of r

We equate

πr² = 64 π

r² = 64 π/π

r² = 64

We square root both sides.

√r² = √64

r =>8 ft

      B... r= 8 ft

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.
