Density of Sphere Calculator:
Enter the values of mass, m(kg) and radius, r(m) to determine the value of Density of sphere, D(kg/m3).
Density of Sphere Formula:
Density signifies the mass of an object per unit volume, typically measured in kilograms per cubic meter. For a sphere, it reflects how much mass is packed into the spherical volume.
A heavier sphere (more mass) will have a higher density (D) if its radius (r) stays the same. Think of a solid steel ball compared to a hollow plastic ball of the same size.
A sphere with a smaller radius (r) will have a smaller volume, even if its mass (m) stays the same. This leads to a higher density (D) because the same amount of mass is packed into a smaller space.
In a solid sphere, more mass packed into a smaller volume (higher density) indicates a denser and potentially stronger material.
The material’s volume acts like a container, confining the mass. A smaller volume makes it harder to fit the same mass, resulting in higher density.
Density of sphere, D(kg/m3) in kilograms per cubic metre is calculated by dividing the mass, m(kg) in kilograms by the volume of the sphere.
Volume of the sphere = (4/3) * pi * r3(m)
Density of sphere, D(kg/m3) = m(kg) / (4/3) * pi * r3(m)
D(kg/m3) = density of sphere in kilograms per cubic metres, kg/m3.
m(kg) = mass in kilogram, kg.
r(m) = radius in metres, m.
Density of Sphere Calculation:
- Find density of sphere:
Given: m(kg) = 500kg, r(m) = 0.5m.
Density of sphere, D(kg/m3) = m(kg) / (4/3) * pi * r3(m)
D(kg/m3) = 500 / (4/3) * 3.14 * 0.53
D(kg/m3) = 500 / 0.5236
D(kg/m3) = 954kg/m3.
- Find mass:
Given: D(kg/m3) = 800kg/m3, r(m) = 0.3m.
Density of sphere, D(kg/m3) = m(kg) / (4/3) * pi * r3(m)
m(kg) = D(kg/m3) * 4/3) * pi * r3(m)
m(kg) = 800 * (4/3) * 3.14 * 0.33
m(kg) = 800 * 0.1131
m(kg) = 90.48kg.
