$6$: $171$: Computer Programming

The volume and area of a cylinder are calculated as:

Volume $=r^{2}h$

Area $=2rh+2r^2$

Given the radius and height of a cylinder as floating$-$point numbers, write a program which outputs the volume and area of the cylinder. Hint: Use the constant pi from the math module in your calculations.

For this lab, you should write two functions, getVolume$($radius$,$ height$)$ and getArea$($radius$,$ height$),$ which receive the necessary numeric inputs and return precise outputs. Do not round within these functions $-$ do your rounding when you print out the values.

Output each floating$-$point value with two digits after the decimal point using the following statement

print $(f^{\text{'}}$ olume $($cubic inches$)$: $\{$yourValue: $\mathrm{.}2f\text{'})$

Ex: If the input is:

$5\mathrm{.}2$

$8\mathrm{.}1$

where $5\mathrm{.}2$ is the radius of the cylinder and $8\mathrm{.}1$ is the height of the cylinder, then the output is:

Volume $($cubic inches$)$: $688\mathrm{.}08$

Surface area $($square inches$)$: $434\mathrm{.}55$
