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}
