a cross-section is taken parallel to the bases of a general cylinder and has an area of 18. If the height of the cylinder is H, what is the volume of the cylinder? Explain your reasoning.

Answers

Answer 1

Answer: ∵ the cross-section is parallel to the bases of the cylinder, then it is congruent to the bases thus, the area of the base of the cylinder is 18.
The volume of a general cylinder is the product of the area of the cylinder’s base times the height of the cylinder,
So the volume of the general cylinder is = 18 H

First of all, your second term is already wrong. When you divided 8x² by 4 ,
you should have written 2x² , not 4x² .

Make that correction, and then divide the whole thing by 'x'.

Then you'll have x² - 2x + 1 = 0 .

You should have no trouble solving that one,
(especially since it's a perfect square)

That gives you two (equal) solutions. But you should also ask yourself:
"Self ! Where is the third solution ? A cubic equation like the original
one needs three solutions."

I'll give you that one:
Look over the original equation, and look at what happens to it when x = 0 .
Then the left side becomes zero, and the equation is 0 = 0 . Since that's a
true statement, " x = 0 " is another solution of the cubic equation, and now
you have all three of them.

divide both sides by 4x:
x^2-2x+1=0
You can either factor, complete the square, or use the quadratic formula.
I'll factor this into (x-1)(x-1)=0
x-1=0, so x=1

Sins = 8x2 and = 2x + a find 5- o

(f × g ) (w) (Please note that I have used w in place of x)
∴((8w²) × (2w+8) × w
(16w³ × 64w²) × w
$16w^(4)$ × 64w³
$1024w^(7)$

terrence finished a word search in 3/4 the time it took frank. charlotte finished the word search in2/3 the time it took terrence.frank finished the word search in 32 min. how long did it take charlotte to finish the word search

Answers

yeah i think the answer could be ;

   2/3 of the time it took Terrence to finish the word search

   time for Terrence; 3/4*32 = 24 min

   time for Charlotte; 2/3*24= 16 min

therefore it took Charlotte 16 min to finish the word.....thx
