Sphere Calculator

Imagine a ball, a perfect, round ball. Got it in your mind? Excellent! Now, you might be wondering how to calculate the volume of this perfect ball. Or maybe you weren’t, but now you are! Fear not, for the sphere calculator is here to save the day!

Sphere Calculation Formula

The formula for the volume of a sphere is V = 4/3 * π * r^3, with V being the volume and r being the radius of the sphere.

Different Categories of Sphere Calculations

Categories Range Interpretation
Small Sphere 0 – 3 inches in radius These are tiny spheres, like marbles.
Medium Sphere 3 – 6 inches in radius These are medium-sized spheres, like a soccer ball.
Large Sphere 6 inches and above in radius These are large spheres, like a beach ball.

Sphere Calculation Examples

Individual Sphere Size Calculation
Bob 3 inch radius V = 4/3 * π * 3^3 = 113.1 cubic inches
Alice 5 inch radius V = 4/3 * π * 5^3 = 523.6 cubic inches
