The volume of a sphere is 381.51 in. If v-(4/3)π=r³ what is the radius

Fudgin [204]

$\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ V=381.51 \end{cases}\implies 381.51=\cfrac{4\pi r^3}{3}\implies 3(381.51)=4\pi r^3 \\\\\\ \cfrac{3(381.51)}{4\pi }=r^3\implies \sqrt[3]{\cfrac{3(381.51)}{4\pi }}=r\implies 4.49923943538655585015\approx r$

Anna [14]

Answer:

The height of the bridge is 71.47 m.

Since the eye of the surveyor is 1.45m creating the horizontal distance, we must add the 1.45 m to the 70.02 m to determine the total height of the bridge.

70.02 m + 1.45 m = 71.47 m

The height of the bridge is 71.47 m.
