Question

The volume of a sphere is a function of it's radius, V=4/3* πr^3. evaluate the function for the volume of a volleyball with radius of 11.3 cm.Round to the nearest tenth.

Answer 1

Volume of sphere = 6040.9cm³

Step-by-step explanation:

Volume of sphere = 4/3* πr³

radius = r = 11.3cm

if π = 3.14

`\begin{gathered} \text{volume = }(4)/(3)*3.14*11.3^3 \\ \end{gathered}`
`\begin{gathered} V\text{ = }\frac{4}{3\text{ }}*3.14*1442.897 \\ V=6040.929cm^3 \end{gathered}`

Rounding to the nearest tenth:

Volume of sphere = 6040.9cm³
