the density of lead is 11.34 g/cm^3 and the density of aluminum is 2.69 g/cm^3. find the radius of lead and aluminum spheres each having a mass of 50 kg.

Density can be defined as the mass per unit volume of a given substance.

The formula is given as:

Density = Mass / volume

The radius of the Aluminum sphere is 16.43cm and the radius of the Lead sphere is 10.17 cm

1 kg = 1000g

50kg = ?

Cross Multiply

50kg × 1000g/ 1 kg

= 50,000g

The mass of lead and Aluminum is 50,000g

The density of Aluminum is 2.69 g/cm³.

Mass of Lead is 50,000g

Volume = Mass/ Density

Volume of Aluminum = 50,000g/ 2.69 g/cm³

Volume of Aluminium = 18587.360595 cm³

The Volume of the Aluminum Sphere = 18587.360595 cm³

The formula to find the radius is given as

(3V/4π)

= (3 × 18587.360595/ 4π)

The radius of the lead sphere = 16.43 cm

The density of lead is 11.34 g/cm³.

Mass of Lead is 50,000g

Volume = Mass/ Density

Volume of Lead = 50,000g/ 11.34 g/cm³

Volume of Lead = 4409.1710758 cm³

The Volume of a Lead Sphere = 4409.1710758 cm³

The formula to find the radius is given as

(3V/4π)

= (3 × 4409.1710758/ 4π)

The radius of the lead sphere = 10.17 cm

Therefore, the radius of the Aluminum sphere is 16.43cm and the radius of the Lead sphere is 10.17 cm.

You have to replace x for each density

Step-by-step explanation:

Density = Mass / Volumen

1,000 g = 1 kg

1,000,000 cm^3 = 1 m^3

g/cm^3 = 1000 kg/m^3

Using density as x

the reporter's right
