Question

A sphere is shown below. = The radius of the sphere is 5/3 inches. What is the approximate volume of the sphere in cubic inches?

Answer 1

58.18 in³

1) Since the volume of a Sphere can be found by

`\begin{gathered} V=(4)/(3)\cdot\pi.r^3 \\ V=(4)/(3)\cdot\pi.\text{ (}(5)/(3))^3 \\ V=(4)/(3)\cdot\pi\cdot(125)/(9) \\ V=(500)/(27)\pi\text{ }\approx58.18 \end{gathered}`

2) SO the volume of that Sphere is approximately 58.18 in³
