What is a Sphere?
A sphere is a three-dimensional shape that is perfectly round and has no edges or corners. It is a closed surface that is symmetrical about its center. The sphere is one of the five regular polyhedra, and it is a fundamental shape in geometry.
The Formula for Calculating the Volume of a Sphere
The formula for calculating the volume of a sphere is:
V = (4/3) * π * r^3
Where:
- V is the volume of the sphere
- π is a mathematical constant approximately equal to 3.14159
- r is the radius of the sphere
Step-by-Step Guide to Calculating the Volume of a Sphere
To calculate the volume of a sphere, follow these steps:
- Identify the radius of the sphere: In this case, the radius of the sphere is 16.2 km.
- Plug in the value of the radius into the formula: V = (4/3) * π * (16.2)^3
- Calculate the value of the radius cubed: (16.2)^3 = 53, 141.968
- Multiply the value of the radius cubed by π: 53, 141.968 * 3.14159 = 167, 011.419
- Multiply the result by 4/3: 167, 011.419 * (4/3) = 222, 747.876
- Round the result to the nearest whole number: 222, 748
