🔎 What Does the Mass and Density Calculator Do?

This tool is designed to calculate:

• Volume of a sphere using the formula:

V=43πr3V = \frac{4}{3} \pi r^3V=34​πr3

• Density using the formula:

ρ=mV\rho = \frac{m}{V}ρ=Vm​

Where:

• VVV = volume (m³)
• rrr = radius (m)
• mmm = mass (kg)
• ρ\rhoρ = density (kg/m³)

The calculator removes the need for manual steps and gives you instant results with precision.

📊 Practical Example

Let’s calculate the density of a steel sphere.

• Mass: 40 kg
• Radius: 0.2 m

Step 1: Calculate Volume

V=43π(0.2)3V = \frac{4}{3} \pi (0.2)^3V=34​π(0.2)3 V=43π(0.008)≈0.03351 m3V = \frac{4}{3} \pi (0.008) \approx 0.03351 \, m^3V=34​π(0.008)≈0.03351m3

Step 2: Calculate Density

ρ=400.03351≈1194.69 kg/m3\rho = \frac{40}{0.03351} \approx 1194.69 \, kg/m^3ρ=0.0335140​≈1194.69kg/m3

✅ Result: The density of the sphere is approximately 1194.69 kg/m³.

This matches the type of result you would instantly see in the calculator.
