The cost of painting the circular traffic sign shown below is $3.50 per square foot. How much, to the nearest dollar, will it cost to paint the sign if its diameter measures 36 inches?

A
$20

B
$25

C
$30

D
$35

Radius is 18

radius squared x pi = area

18 x 18 = 324

324 x pi = 1017.876

1017.876/144=7

We divide by 144 because it is converting with square units instead of units so we square the conversion

7 x 3.5 = 24.5

round up to 25

hope this helps your answer is 25

Step-by-step explanation:

step-by-step explanation:

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.
