Answer
The volume of the sphere is $36\pi \text{ ft}^3$.
The surface area of the sphere is $36\pi\text{ ft}^2$.
Work Step by Step
The volume $V$ of a sphere is given by the formula $V=\frac{4}{3}\pi{r}^3$ where $r$ the radius.
Substitute the given values to obtain:
$V=\dfrac{4}{3}\pi (3\text{ ft})^3$
$V=36\pi \text{ ft}^3$
Hence, the volume of the sphere is $36\pi \text{ ft}^3$.
The surface area $S$ of a sphere is given by the formula $S=4\pi{r}^2$ where $r$ is the radius.
Substitute the given values to obtain:
$S=4\pi (3\text{ ft})^2$
$S=36\pi \text{ ft}^2$
Hence, the surface area of the sphere is $36\pi\text{ ft}^2$.
