Answer:

15 kg

Step-by-step explanation:

Radius of a solid sphere : mass of a solid sphere

3 cm : 9 kg

Find the mass of a sphere of the same material of radius 5 cm

Radius of a solid sphere : mass of a solid sphere

5 cm : x kg

Equate both ratios to find x

3 cm : 9 kg = 5 cm : x kg

3/9 = 5/x

3 * x = 9 * 5

3x = 45

x = 45/3

x = 15 kg

The mass of a sphere of the same material of radius 5 cm is 15 kg
