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 3 ways to calculate volume?**

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

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

### 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.

- Result is positive zero, if the argument is positive zero or negative zero.
- Result is positive infinity if the argument is infinite.
- 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

- public class test.
- {
- public static void main(String args[])
