Anita has a string of lights that is 30 ft long if she makes a complete circle with these lights what is the approximate radius of the largest circle she can make

radius ≈ 4.75 ft

Step-by-step explanation:

The circumference of a circle is the perimeter of a circle, or the outside measure of a circle.  With the amount of lights Anita has, the largest circumference of a circle she can make is 30 ft.  The formula for circumference is:  C = 2πr, where 'r' = radius.  

Filling in the maximum measure:

30 = 2πr or 15 = πr

Divide by π on both sides: 15/π = πr/π  or r ≈ 4.75ft

i would pic false cause it goes down towards negative

step-by-step explanation:

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405
