Need help on these 4 math problems:

Find the surface area S of the solid formed by revolving the region bounded by the graph of y : 5x + 4, the xaxis, and the given lines 3: : 0 and x : 1 about the xaxis. (Express numbers in exact form. Use symbolic notation and fractions where needed.) Find the surface area S of the solid formed by revolving the region bounded by the graph of y = 1',\" 2x. the xaxia, and the given lines 3: = 2 and x = 5 about the xaxia. (Express numbers in exact form. Use symbolic notation and fractions where needed.) 5 Find the surface area S of the solid formed by revolving the region bounded by the graph of y = 8 x. the xaxis, and the given lines 3: = 1 and x = 3" about the xaxis. (Express numbers in exact form. Use symbolic notation and fractions where needed.) 5 Use the arc length formula to find the length of the graph of the function x-25 + 3 y =x from x = 64 to x = 343. (Use symbolic notation and fractions where needed.) S =
