the surface area of the sphere with the

radius r is

$4\pi {r}^{2}$

so, the surface area of the sphere with radii 9cm is

$4 \times \pi \times {9}^{2}$

$= 4 \times 3.14 \times 9 \times 9$

$4 \times 3.14 \times 81$

$324 \times 3.14$

$1017$

and the volume of the sphere is

$(4 \div 3)\pi {r}^{3}$

$= 3052$
