Question

6. Find the volume of the following sphere. Leave answers in terms of n.42 cm

Answer 1

The volume of a sphere is:

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

From the figure we notice that the radius is 21 cm. Then we have that:

`\begin{gathered} V=(4)/(3)\pi(21)^3 \\ =12348\pi \end{gathered}`

Therefore the volume is 12348pi cubic centimeters.
