Apply the order of operations and answer the questions. The area of a circle of radius 0.6 feet is given by the expression \(\pi(0.6)^{2}\). Evaluate the expression and interpret the answer by rounding the result to two decimal places.

Solve the equations. More than one step is needed in each case. $$3 x+1=13$$

Consider a variable \(x\) where \(x\) represents the whole numbers from 0 to 20. Stated mathematically, the possible values of \(x\) are $$x=0,1,2, \ldots, 19,20$$ For each of the phrases, write an inequality and then determine which values satisfy that inequality. \(x\) is less than 3
