Density = 2.7g/cm3
mass =8.1grams
from density =(mass)/volume 
we can determine the volume of aluminium by simply changing the subject of the subject of the formula from density to volume 
so we have 

volume=mass/density
            =(8.1grams)/(2.7g/cm3)
            =3cm3

FromTheMoon [43]
Object Motion: 25 m/s

Circumference of Circle: 
1/4 Circumference of Circle in 1 second = 25 meters
25 meters times 4 = Circumference of Circle 
Circumference = 100 meters

Formula to Find Circumference of Circle: (work opposite)
C = 2<span>πr

100 = </span>2πr          divided
100/2π = r         simplify
50/π = r         (exact radius)

Answer:
50/π meters = r         (exact radius)
