8 0

Answer:

75 inches

Step-by-step explanation:

with this we use change of subject

V=1/3

Pie=3.14

radius =3

height =8

so therefore

V=1/3 ×3.14×3×3×8

V=75.36

If u+v+w=0, show that u x v = v x w = w x u
nydimaria [60]
\mathbf u+\mathbf v+\mathbf w=\mathbf 0

Take the cross product of both sides with \mathbf u,\mathbf v,\mathbf w, respectively. By the distributive property of the cross product, you have the system

\begin{cases}\mathbf u\times\mathbf u+\mathbf u\times\mathbf v+\mathbf u\times\mathbf w=\mathbf 0\\\mathbf v\times\mathbf u+\mathbf v\times\mathbf v+\mathbf v\times\mathbf w=\mathbf 0\\\mathbf w\times\mathbf u+\mathbf w\times\mathbf v+\mathbf w\times\mathbf w=\mathbf 0\end{cases}\iff\begin{cases}\mathbf u\times\mathbf v+\mathbf u\times\mathbf w=\mathbf 0\\\mathbf v\times\mathbf u+\mathbf v\times\mathbf w=\mathbf0\\\mathbf w\times\mathbf u+\mathbf w\times\mathbf v=\mathbf 0\end{cases}

since \mathbf x\times\mathbf x=\mathbf0 for any vector \mathbf x.

And because the cross product is anticommutative, you have

\begin{cases}\mathbf u\times\mathbf v-\mathbf w\times\mathbf u=\mathbf 0\\-\mathbf u\times\mathbf v+\mathbf v\times\mathbf w=\mathbf0\\\mathbf w\times\mathbf u-\mathbf v\times\mathbf w=\mathbf 0\end{cases}

from which it follows immediately that

\mathbf u\time\mathbf v=\mathbf v\times\mathbf w=\mathbf w\times\mathbf u
