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:

V=\frac{1}{3}\pi r^2h

Putting values

V=\frac{1}{3}*\frac{22}{7}*(4)^2*10\\V=\frac{22}{21}*16*10\\V=167.62\ cm^3

Mass of Steel Cone:

M_s=Density\ of\ steel*Volume\\=7.75*167.62\\=1299.055\ grams

Mass of Granite Cone:

M_g=Density\ of\ granite*Volume\\=2.75*167.62\\=460.955\ grams

Difference between masses of both cones

D = M_s-M_g\\=1299.055-460.955\\=838.1\ grams

Rounding off to nearest gram: 838 grams

The difference between masses of both cones is: 838 grams

Keywords: Volume, Mass

Ahhhh help everyone help me solve this ....​
vovangra [49]

Answer:

y =  \frac{18 {w}^{2}  {x}^{2}  {z}^{2} }{25}

Step-by-step explanation:

\frac{3wx}{ \sqrt{2y} }  =  \frac{5}{2z}  \\  \\  \sqrt{2y}  \times 5 = 3wx \times 2z \\  \\  \sqrt{2y}   \times 5 = 6wxz \\  \\  \sqrt{2y}  =  \frac{6wxz}{5}  \\  \\  {( \sqrt{2y} })^{2}  =  {( \frac{6wxz}{5} })^{2}  \\  \\ 2y =  \frac{36 {w}^{2} {x}^{2} {z}^{2}   }{25}  \\  \\  \\  y =  \frac{36 {w}^{2} {x}^{2}  {z}^{2}  }{25}  \div 2 \\  \\  \\ y =  \frac{36 {w}^{2} {x}^{2} {z}^{2}   }{25}  \times  \frac{1}{2}  \\  \\  \\ y =  \frac{36 {w}^{2} {x}^{2}  {z}^{2}  }{50}  \\  \\  \\ y =  \frac{18 {w}^{2} {x}^{2}   {z}^{2} }{25}
