Answer 1

printf("The area of the circle is : %.3f km²" ,result/1000000.0 );

//you know %f gives a float, the .3 makes it print only 3 places after the decimal point.

Answer 3

#include <stdio.h>

float aoc(float );
int main()
{
float r,result;
printf ("Enter radius of a circle in meters : \n");
scanf("%f",&r);
result = aoc(r);
printf("The area of the circle is :%f" ,result );
return 0;
}
float aoc(float q)
{
float area , pi;
pi=3.14;
area= pi*q*q;
return area ;
}

Answer 4

Is this homework?

The q&a is not for us writing code for you. We help you fix code you already have.

Answer 5

I can't figure out how to incorporate the conversation of meters to km²😥

Answer 6

G'day Martinkim could you copy+paste that code into a SoloLearn "code bit" then edit that post to have a link to your code bit instead of the code in the text. Much much easier for us to help you....
