Enter the program below

$2)$ Run program using input $=1.$ Then, type $10($radius$)$

$3)$ Add function for area of square. Then, add function for area of sphere

$4)$ Test both functions $($input $=10).$

$5)$ Make sure your calculation is accurate

i need to see the out put and please run the program in C
