The difference between masses of both cones is: 838 grams
Step-by-step explanation:
As both cones have same height and radius. Both will have same volume
Here
r=4 cm
h= 10 cm
The volume is given by:
[tex]V=\frac{1}{3}\pi r^2h[/tex]
Putting values
[tex]V=\frac{1}{3}*\frac{22}{7}*(4)^2*10\\V=\frac{22}{21}*16*10\\V=167.62\ cm^3[/tex]
Mass of Steel Cone:
[tex]M_s=Density\ of\ steel*Volume\\=7.75*167.62\\=1299.055\ grams[/tex]
Mass of Granite Cone:
[tex]M_g=Density\ of\ granite*Volume\\=2.75*167.62\\=460.955\ grams[/tex]
Difference between masses of both cones
[tex]D = M_s-M_g\\=1299.055-460.955\\=838.1\ grams[/tex]
Rounding off to nearest gram: 838 grams
The difference between masses of both cones is: 838 grams
