The ball in shape of sphere. So radius of sphere is r = 9 in.

The formula for the volume of sphere is,

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

Substitute the value in the formula to obtain the volume of ball.

$\begin{gathered} V=(4)/(3)\pi\cdot(9)^3 \\ =3053.628 \\ \approx3053.63 \end{gathered}$

The formula for the surface area of ball is,

$S=4\pi\cdot(r)^2$

Substitute the value in the formula to obtain the surface area.

$\begin{gathered} S=4\pi\cdot(9)^2 \\ =1017.876 \\ \approx1017.88 \end{gathered}$

So answer.

Volume = 3053.63 inch cube

Surface area = 1017.88 inch square.
