How do you calculate volume in Java?

What is the formula of volume?

Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

How do you calculate the volume of a cylinder in Java?

Java Program

  1. public class cylinder{
  2. public static void main(String args[])
  3. {
  4. int height=38;
  5. int radius=35;
  6. double pie=3.14285714286;
  7. double volume=pie*(radius*radius)*height;
  8. System.out.println(“Volume of the cylinder=”+volume);

What is a formula for the volume of a sphere?

The formula for the volume of a sphere is V = 4/3 πr³. See the formula used in an example where we are given the diameter of the sphere.

How do you calculate surface area in Java?

Java Surface Area of a Cylinder

If we know the radius and height of the cylinder, then we can calculate the surface area of a cylinder using the formula: Surface Area of a Cylinder = 2πr² + 2πrh (Where r is a radius and h is the height of the cylinder).

How do you calculate the volume of a tray?

To find the volume of a box, simply multiply length, width, and height — and you’re good to go! For example, if a box is 5×7×2 cm, then the volume of a box is 70 cubic centimeters. For dimensions that are relatively small whole numbers, calculating volume by hand is easy.

How do you find the volume of a 3D shape?

Calculating Volume for Various 3D Objects

  1. Cube. Volume = s3 = s x s x s. Where s is the length of the side of the cube. …
  2. Rectangular Prism. Volume = l x w x h. …
  3. Cylinder. Volume = area of base x h. …
  4. Sphere. Volume = 4/3 x pi x r3
  5. Cone. Volume = 1/3 x pi x r2 x h. …
  6. Pyramid. Volume = 1/3 x area of base x h.

Is vowel function in Java?

In Java, you use double quotes (” “) for strings and single quotes (‘ ‘) for characters. Now, to check whether ch is vowel or not, we check if ch is any of: (‘a’, ‘e’, ‘i’, ‘o’, ‘u’) . This is done using a simple if..else statement. We can also check for vowel or consonant using a switch statement in Java.

What is the area and volume of a cylinder?

A cylinder’s volume is π r² h, and its surface area is 2π r h + 2π r². Learn how to use these formulas to solve an example problem.

Why is it 4 3 for volume of a sphere?

Since the cylinder/cone and hemisphere have the same height, by Cavalieri’s Principle the volumes of the two are equal. The cylinder volume is πR3, the cone is a third that, so the hemisphere volume is 23πR3. Thus the sphere of radius R has volume 43πR3.

How do you find the volume for a rectangular prism?

To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

How do you find the volume of a sphere in Java?

Java Program

  1. public class sphere{
  2. public static void main(String args[])
  3. {
  4. int radius=48;
  5. double pie=3.14285714286;
  6. double volume=(4.0/3.0)*pie*(radius*radius*radius);
  7. System.out.println(“Volume of the sphere=”+volume);
  8. }

What is the volume of the cone?

Volume of a cone: V = (1/3)πr2h.

How do you find the surface area of a cube in Java?

Surface Area of a Cube = 6l² (Where l is the Length of any side of a Cube). Area of a square = l² Since the Cube made of 6 equal squares, Surface Area of a Cube = 6l²
