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:

$V=\frac{4}{3}\pi r^3$

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

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

Therefore the volume is 12348pi cubic centimeters.
