Question

Am I right?

A cylinder labeled X has a height of 10 inches and a radius of 15 inches. Another cylinder labeled Y has a height of 40 inches and a radius of 60 inches.

The volume of cylinder Y is _______ times the volume of cylinder X.

The answer is 1.06

Answer 1

WHY MIGHT YOU THINK THAT YOU'RE WRONG?

Answer 2

O-O....

Answer 3

I think I'm wrong, because I'm not sure if I used the proper formula...?

Answer 4

Answer 5

@nincompoop caps off please

Answer 6

I tried searching already but failed to find it;;

Answer 7

ARAVIND, THERE'S NO RULE AGAINST USING UPPER CAPS.

Answer 8

@Nurali , can you help with this problem?

Answer 9

Though it seems like you are shouting

Answer 10

@TheHero given any figure volume is got by the product of base area and height .Remember!

Answer 11

Base of a cylinder is a circle :Arepi *r*r

Answer 12

*Area=pi*r*r

Answer 14

height=h

Answer 15

So volume=pi *r*r*h

Answer 16

3.14*15*15= 707.14
Volumi: 3.14*15*15*10= 7071.428

Answer 17

Just divide the volume of Y by the volume of X.

Pi x 60 x 60 x 40 / Pi x 15 x 15 x 10.


If the final answer is 1.06 then ur correct.

Y : X = 1.06 : 1

Which, by law of proportions means Y = 1.06 X; try it out

Answer 18

3.14*60*60*40=452571.428

Answer 19

;~; I did get 1.06 previously, I wasn't sure if it was right though.

Answer 20

why not ?

Answer 21

@AravindG somehow i think 1.06 is not right..radius itself is 4 times or something;

Answer 22

D: Because, I just guessed the formula!

Answer 23

If you get it by proper calculation .Why doubt it ?

Answer 24

Oh ok ....Now I gave you the correct formula .Calculate again?

Answer 25

I got 64.

Answer 26

Yes i think Y is 64 times of X's volume..i think its correcto

Answer 27

you are right !
