Round 336041 to the nearest ten thousands

Kapil needed to buy a long wooden beam. he went to two sawmills that each charge an initial fee plus an additional fee for each meter of wood. the following equation gives the price (in dollars) of a wooden beam from the first sawmill as a function of its length (in meters). p = 5+20xp=5+20x

100 points, hi, i’m not sure how to get the equation from the graph and table.

How do you find the circumfrance of a circle?
