A toilet paper company sells rolls of toilet paper where the cardboard portion in the middle has a diameter of 1.8 inches and a height of 3.75 inches. How many square inches of cardboard would there be in a package of 24 rolls of toilet paper? Round your answer to the nearest roll.     

Area of one tube  =  circumference times length  =  1.8 • π • 3.75     

                                                                              =  1.8 • 3.1416 • 3.75     

                                                                              =  21.2058     

Area of 24 tubes  =  24 times Area of one tube    =  24 • 21.2058     

                                                                              =  508.9392  —>  rounds to 509
