Why is the volume of a sphere 4/3 PI r3?

The volume V of a sphere is four-thirds times pi times the radius cubed. The volume of a hemisphere is one-half the volume of the related sphere. Note : The volume of a sphere is 2/3 of the volume of a cylinder with same radius, and height equal to the diameter.

What is formula for 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 you refer to the different dimensions does not change the calculation: you may, for example, use ‘depth’ instead of ‘height’.

How do you find the volume of a spherical shell?

Volume of spherical shell =4/3π(R3−r3). R=radius of outer part r=radius of inner part

  1. The radius of the smaller circle is 4 cm and the radius of the larger circle is 8 cm.
  2. Volume of a spherical shell with outer and inner radii R and r respectively is:
  3. A spherical shell 2 m thick has an outer diameter of 12 m.

What is Pi in Java?

PI is a static final double constant in Java, equivalent to in π Mathematics. Provided by java. lang. Math class, Math. PI constant is used to carry out multiple mathematical and scientific calculations like finding the area & circumference of a circle or the surface area and volume of a sphere.

How do you find the surface area and volume of a cylinder in Java?

The Java Volume of a Cylinder
If we know the height of a cylinder then we can calculate the volume of a cylinder using the formula: Volume of a Cylinder = πr²h. The Lateral Surface Area of a Cylinder = 2πrh. We can calculate the Top Or Bottom Surface Area of a Cylinder = πr²

Which formula is πr2h?

Use the existing mathematical formula for the volume of a cylinder, V = πr2h, where r is the radius of the cylinder, h is the height, and π is the constant Pi.

Why is a sphere 2/3 of a cylinder?

Multiple Choice: 2/3 because the volume of the cylinder times 2/3 equals the volume of the sphere. 3. Multiplying the volume of a cylinder by 2/3 will give you the volume of a sphere with the same radius.

What are the 3 formulas for volume?

Shapes Volume Formula Variables
Rectangular Solid or Cuboid V = l × w × h l = Length w = Width h = Height

What are 3 ways to calculate volume?

Depending on your object shape, you can use different formulas to calculate volume:

  1. Cube volume = side.
  2. Cuboid (rectangular box) volume = length × width × height.
  3. Sphere volume = (4/3) × π × radius.
  4. Cylinder volume = π × radius2 × height.
  5. Cone volume = (1/3) × π × radius2 × height.
  6. Pyramid volume = (1/3) × base area × height.

How do you find the volume and area of a sphere?

You will find a point equidistant from any point on the surface of a sphere.
Formulas of a Sphere.

Sphere Formulas

How do you put Math in Java?

out. println( “pow(2.0, 2.0) is ” + Math. pow( 2.0 , 2.0 )); System.
This method can handle all the data types.

  1. Result is positive zero, if the argument is positive zero or negative zero.
  2. Result is positive infinity if the argument is infinite.
  3. Result is NaN, if passed argument is NaN.

Does Java recognize PI?

Java does not recognize Pi , pi , or pie . Also, PI is the name of a variable, not a method, so it doesn’t have parentheses. The same is true for the constant Math. E , which approximates Euler’s number.

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

JAVA

  1. public class test.
  2. {
  3. public static void main(String args[])
  4. {
  5. float r, h, surfacearea;
  6. r = 2;

What is ΠR 2h?

Cylinder’s volume is given by the formula, πr2h, where r is the radius of the circular base and h is the height of the cylinder.

What is 2πrh?

The radius ‘r’ of a cylinder is the radius of its base. Now, the area of the rectangle = length × breadth. 2πr is the circumference of the circle and h is the height. Area of the curved surface will be = 2πr × h = 2πrh.

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

You can use the formula for the volume of a cylinder, π ⋅ radius 2 ⋅ height , to find the formula for the volume of a sphere: Volume of a Sphere Explanation V = 2 3 ( π ⋅ radius 2 ⋅ height ) The volume of a sphere is two-thirds the volume of a cylinder.
