Iron ball

The iron ball weighs 100 kilograms. Calculate the volume, radius, and surface if the iron's density is h = 7.6g/cm3.

Final Answer:

V =  13.1579 dm3
r =  1.4645 dm
S =  26.9531 dm2

Step-by-step explanation:

m=100 kg ρ=7.6 g/cm3 kg/m3=7.6 1000  kg/m3=7600 kg/m3  m = ρ V  V1=m/ρ=100/7600=7610.0132 m3  V=V1 dm3=V1 1000  dm3=0.0132 1000  dm3=13.158 dm3=13.1579 dm3
V = 34   π   r3  r=34πV 3=34 3.141613.1579 3=1.4645 dm
