Answer:

public static double areaSum(Circle c1, Circle c2){

 double c1Radius = c1.getRadius();

 double c2Radius = c2.getRadius();

 return Math.PI * (Math.pow(c1Radius, 2) + Math.pow(c2Radius, 2));

public static void main(String[] args){

 Circle c1 = new Circle(6.0);

 Circle c2 = new Circle(8.0);

  areaSum(c1,c2);

 }

Because filling a pool/pond with water requires much more water than normal usage, your local city charges a special rate of $0.
nevsk [136]

Answer:

In C:

#include <stdio.h>

int main(){

   float length, width, depth,poolvolume,watervolume,charges;

   printf("Length (feet) : ");    scanf("%f",&length);

   printf("Width (feet) : ");    scanf("%f",&width);

   printf("Depth (feet) : ");    scanf("%f",&depth);

   poolvolume = length * width* depth;

   watervolume = length * width* (12 * depth - 3)/12;

   charges = 100 + 0.77 * watervolume;

   printf("Invoice");

   printf("\nVolume of the pool: %.2f",poolvolume);

   printf("\nAmount of the water needed: %.2f",watervolume);

   printf("\nCost: $%.2f",charges);

   printf("\nLength: %.2f",length);

   printf("\nWidth: %.2f",width);

   printf("\nDepth: %.2f",depth);

   printf("\nMr. Royal [Replace with your name] ");

   return 0;}

Explanation:

This declares the pool dimensions, the pool volume, the water volume and the charges as float    

float length, width, depth,poolvolume,watervolume,charges;

This gets input for length

   printf("Length (feet) : ");    scanf("%f",&length);

This gets input for width

   printf("Width (feet) : ");    scanf("%f",&width);

This gets input for depth

   printf("Depth (feet) : ");    scanf("%f",&depth);

This calculates the pool volume

   poolvolume = length * width* depth;

This calculates the amount of water needed

   watervolume = length * width* (12 * depth - 3)/12;

This calculates the charges

   charges = 100 + 0.77 * watervolume;

This prints the heading Invoice

printf("Invoice");

This prints the volume of the pool

   printf("\nVolume of the pool: %.2f",poolvolume);

This prints the amount of water needed

   printf("\nAmount of the water needed: %.2f",watervolume);

This prints the total charges

   printf("\nCost: $%.2f",charges);

This prints the inputted length

   printf("\nLength: %.2f",length);

This prints the inputted width

   printf("\nWidth: %.2f",width);

This prints the inputted depth

   printf("\nDepth: %.2f",depth);

This prints the name of the programmer

   printf("\nMr. Royal [Replace with your name] ");

   return 0;}
