Question

The radius, R, of a sphere is 5.7 cm. Calculate the sphere's volume, V.Use the value 3.14 for r, and round your answer to the nearest tenth. (Do not round any intermediate computations.)

Answer 1

The volume formula of a sphere is :

`V=(4)/(3)\pi r^3`

From the problem, the radius of the sphere is r = 5.7 cm

Using the formula above :

`\begin{gathered} V=(4)/(3)(3.14)(5.7)^3 \\ V=775.3 \end{gathered}`

ANSWER :

775.3 cm^3
