Question

Use 3.14 and round to the nearest tenth if necessary.

Answer 1

The radius of the sphere is half the diameter. In this case the diameter is 11 cm, then we have:

`r=(11)/(2)=5.5`

Therefore, the radius of the sphere is 5.5 cm

The volume of the sphere is given by:

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

Pluggin the values of pi and the radius we found we have that:

`\begin{gathered} V=(4)/(3)\left(3.14\right)\left(5.5\right)^3 \\ V=696.6 \end{gathered}`

Therefore the volume of the sphere is 696.6 cubic cm.
