Question

find the height for with the given radius 3cm n volume 350cm3

Answer 1

volume of a cylinder, sphere ?

Answer 2

cylinder n i must find the height and the surface area.. but they only gave the radius 3cm n volume 350cm3

Answer 3

kk, smartie. How do you think this problem should be solved using the formula given ?

Answer 4

\[V=\pi r ^{2}h\] for cylinder, kk, lv

Answer 5

surface area= \[A=2πr2 + 2πrh = 2πr(r + h)\]

Answer 6

well wen i try it,it give my problem so can u work it out for me please

Answer 7

yes, I could I would prefer if you understood it so you won't need to worry. Can you make h the subject of the formula in the volume equation ?

Answer 8

i cnt get the formula out of the volume equation i guess pir2h/2πr2+2πrh=2πr(r+h)

Answer 9

\[h=V/(\pi r ^{2})\]

Answer 10

tanx so can u work it out for me nw please

Answer 11

lol! Y don't you give it go first. Just plug volume and radius into the equation

Answer 12

kool loool

Answer 13

350/pir2

Answer 14

r=3=> r^2 =9

Answer 15

so datz the height 9cm

Answer 16

h=12.4cm. now you have h and find A, the surface area

Answer 17

so nw wat is the suface area nw

Answer 18

yh, plug in the values of h=12.4 and r=3 into
A=2πr2 + 2πrh = 2πr(r + h) , where ever you h and r replace with values kk

Answer 19

so it wld be 2pi32 plus 2pi3 12.4=2pir (3 plus 12.4) is datz wat u meant

Answer 20

what is yr pi given as ? 3.14 or 22/7

Answer 21

3.14

Answer 22

so nw rewrite the equation using 3.14 as pi
for me please

Answer 23

kk, A=2*(3.14)*(3)*(3+12.4)=290.14cm^2

Answer 24

kool tanx

Answer 25

yh, no p

Answer 26

kool

Answer 27

find the height and surface area with the radius of 2cm n volume 350cm3

Answer 28

it's the same steps, just change the numbers

Answer 29

kk, lv!

Answer 30

can u work it out for me please cuz i am doin another part of the project cuz it is due tomorrow pleasee

Answer 31

\[h=350/((3.14)\times(2)^{2})=350/(3.14\times4)=27.866cm\]
\[A=2\pi r(r+h)= 2\times(3.14)\times 2\times(2+27.866)=375.12cm ^{2}\]

Answer 32

tanx much

Answer 33

find the height n the surface area with the radius 4cm n volume 350cm3

Answer 34

please reply
