WebNov 10, 2024 · Calculate the arc length of the graph of f(x) over the interval [0, 1]. Round the answer to three decimal places. Solution We have f′ (x) = 3x1 / 2, so [f′ (x)]2 = 9x. Then, the arc length is Arc Length = ∫b a√1 + [f′ (x)]2dx = ∫1 0√1 + 9xdx. Substitute u = 1 + 9x. Then, du = 9dx. When x = 0, then u = 1, and when x = 1, then u = 10. Thus, WebTo calculate the length (= the arc length) you need to calculate the whole circumference first and then multiply it by 3/4 to find the length you really want: Whole circumference = 2*Pi*radius = 8*Pi = approx. 25.13dm, The length that you need: (8*Pi) * (3/4 ) = 6*Pi = approx. 18.85dm. Hope that helps!
