Answer:
#include <stdio.h>
int main() {
const float square_feet;
printf("Enter area in square feets: ");
// reads and stores input area
scanf("%f", &square_feet);
float acres= square_feet/43560;
// displays area in acres
printf("area in acres is: %.2f", acres);
return 0;
}
Explanation:
code is in C language.
double slashed '//' lines are not code but just comments to understand what it mean in code or for explanation purpose

Answer:
The answers to 1st question and part 2A is given. However, the 2B is not given complete and thus cannot be answered.
Explanation:
UNION is a keyword used in C Language to have a commonly shared memory that can be used by multiple elements. It is a data-type that allows different data types to use the same shared memory location.
Importance: If you want to minimize the use of memory by sharing it between different datatype variables, then use UNION. For Ex. Let's suppose I want to use 2 variables a and b of type char and int respectively. Now, suppose int takes memory space of 2 bytes and char takes 1 byte then the total amount of memory needed = 2 + 1 = 3 Bytes. But, we want to first make use of a, and once done, we want to declare variable b. We can limit the memory use by declaring a memory space of 2 bytes (max of a and b). First, we can use this space to store the int variable and when done with it, we can use it to store the char variable.
PART 2A
typedef struct{
int partNum;
char partName[25];
} partin;
#define Partin partin
Question
Student presentation concepts from another source
Letitia - a step-by-step process of breaking down glucose into energy
Mana - repeating process of the steps of the cell division, going from interphase to division, and back to interphase.
Paul - a series of organisms that show similar characteristics and compare them to those that do not
Which best describes the SmartArt graphic layout each student should use?
Answer:
Letitia would use a process, Maria would use a cycle, and Paul would use a relationship.
Explanation:
Letita's assignment requires her to show how glucose can be broken down into energy, this requires a series of steps in s linear fashion, meaning it would be best suited to a process-style diagram.
Marta's project involves showing the steps of the cell cycle: the clue is in the name. This process is not linear, and instead repeats itself, meaning it fits to a cycle diagram (i.e. a circular diagram)
Paul is comparing and contrasting different organisms. Therefore, he should use a relationship diagram to show shared characteristics as well as features that differ.
