Volume of Sphere

radius = 2

Answer:

33.51 cubic units

Shape Visualization

Sphere with radius 2 units

Step-by-Step Solution

1

Identify the formula for volume of a sphere

V = (4/3)πr³
2

Cube the radius

r³ = 2³ = 8
3

Multiply by π

π × 8 = 25.13
4

Multiply by 4/3

(4/3) × 25.13 = 33.51
5

Final answer

Volume = 33.51 cubic units

Formula Used

V = (4/3)πr³

This formula calculates the volume of a sphere.

Real-World Applications

1

A spherical ball with 2 cm radius has 33.51 cubic centimeters of volume

2

A globe with 2 inch radius = 33.51 cubic inches

Understanding Sphere Volume

The volume of a sphere is a fundamental concept in geometry. Volume measures the amount of space inside a 3D object, expressed in cubic units.

By using the formula V = (4/3)πr³, we can quickly and accurately calculate the volume for any sphere when we know the required measurements.
