Question

Write a function ""volCylinder"" that takes twofloats""r""for the radius and ""h""for the height of the cylinder and returnsthe volumeof the cylinder. You can check the Wikipedia page to learn about volume calculation of the cylinders:

Answer 1

Answer:

   public static double volCylinder(double r, double h){

       double volCylinder = Math.PI*(r*r)*h;

       return volCylinder;

   }

Explanation:

Using Java programming language

The function (method) is declared to accept two double parameters for radius and height

Using the formula Vol = $\pi r^{2} h$ The volume is calculated and returned.

See a complete java code with a main method below

public class num7 {

   public static double volCylinder(double r, double h){

       double volCylinder = Math.PI*(r*r)*h;

       return volCylinder;

   }

   public static void main(String[] args) {

   double radius =5.1;

   double height = 7.1;

       System.out.println("The volume of the cylinder is: "+volCylinder(radius,height));

   }

}

Answer 2

Answer:

def volCylinder(r, h):

   return 3.14 * r * r * h;    

radius = float(input("Enter the radius: "))

height = float(input("Enter the height: "))

print("The volume of the cylinder is: "+ str(volCylinder(radius, height)))

Explanation:

- Inside the function, calculate the volume of the cylinder using the formula and return the result.

- Then, take inputs from the user for radius and height as float numbers

- Call the function and print the result
