<span>You did not include the equations that you want to assess whether they can be used to solve for the radius (r). Likely, the equation of the circumference, C = 2*Pi*r is included, if so => r = C / (2*Pi). If you round Pi to 3.14, the equation may be written r = C / 6.28.</span>

Firlakuza [10]
<span>1. W2 is a form every empoyer send to his employees that reports the annual wagges of the employees and the amount of taxes. This W2 form is sent at the end of the year. The employees get at least two copies of this form. One copy is for the employee and the other is for IRS (Internal revenue Service) to report the wages. 2. John's employeer sent John the W-2 form. Every employer is obligated to deliver W2 form to all of his employees. John can get copy of the W-2 form for IRS (Internal Revenue Service). This is done for a fee. 3/ In order to know how much John did in wages in the 2014 we must have knowledge of John's salaty. Without this information we can not clculate the wages. </span>
