ANSWER

$\begin{gathered} SA=1017.36\operatorname{cm}^2 \\ V=3304.8\operatorname{cm}^3 \end{gathered}$

Step-by-step explanation

We want to find the surface area and volume of the sphere given.

The radius of the sphere is 9 cm.

To find the surface area, apply the formula:

$SA=4\cdot3.14\cdot r^2$

where r = radius

Therefore, we have that:

$\begin{gathered} SA=4\cdot3.14\cdot9^2 \\ SA=1017.36\operatorname{cm}^2 \end{gathered}$

To find the volume, apply the formula:

$V=(4)/(3)\cdot3.14\cdot r^3$

Therefore, we have that:

$\begin{gathered} V=(4)/(3)\cdot3.14\cdot9^3 \\ V=3304.8\operatorname{cm}^3 \end{gathered}$
