A cylinder has a base diameter of 8ft and a height of 20ft. What is its volume in cubic ft, to the nearest tenths place?

jenyasd209 [6]

Answer:

$4022.9$

Step-by-step explanation:

Volume of a cylinder is given by cross sectional area multiplied by height hence

V=Ah

Since the cross sectional area of

$A=\pi r^{2}$

Substituting the formula for A into formula for volume then

$V=Ah=\pi r^{2}h$

Substituting 8ft for r and 20 ft for h then

$V=Ah=\pi 8^{2}\times 20=4022.8571428571\ ft^{3}\approx 4022.9\ ft^{3}$

Rounded off to the nearest tenths, the volume is equivalent to

$4022.9$

Mark the statement either true (in all cases) or false (for at least one example). If false, construct a specific example to sho

LUCKY_DIMON [66]

Answer with Step-by-step explanation:

We are given that $v_1,v_2,..,v_4$ are in $R^4$ and $v_1,v_2,v_3$ is linearly dependent then {v_1,v_2,v_3,v_4}[/tex] is also linearly dependent.

We have to find that given statement is true or false.

Dependent vectors:Dependent vectors are those vectors in which atleast one vector is a linear combination of other given vectors.

Or If we have vectors $x_1,x_2,....x_n$

Then their linear combination

$a_1x_1+a_2x_2+.....+a_nx_n=0$

There exist at least one scalar which is not zero.

If $v_1,v_2,v_3$ are dependent vectors then

$a_1v_1+a_2v_2+a_3v_3=0$ for scalars $a_1,a_2,a_3$

Then , by definition of dependent vectors

There exist a vector which is not equal to zero

If vector $v_3$ is a linear combination of $v_1\;and \;v_2$ , So at least one of vectors in the set is a linear combination of others and the set is linearly dependent.

Hence, by definition of dependent vectors

{ $v_1,v_2,v_3,v_4$ } is linearly dependent.

Option B is true.

Evan bought a bag of Skittles, ate 13 of them, then distributed them evenly into 4 bowls. If there are 64 Skittles in each bowl,

Anna35 [415]

There were 269 skittles in the bag originally.

Step-by-step explanation:

Skittles ate by Evan = 13

No. of bowls = 4

No. of skittles in each bowl = 64

As the skittles are distributed evenly therefore,

Skittles in 4 bowls = 64*4

Skittles in 4 bowls = 256

Total skittles = Skittles in 4 bowls + skittles ate by Evan

Total skittles = 256 + 13

Total skittles = 269

There were 269 skittles in the bag originally.
