WebWhat is the arc length that has a radius of 2, and an angle of 1 radian? Answer Substitute the values for radius and angle into the relationship between arc length, radius and angle at the top of the page: 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,
