- anonymous

sorry|dw:1352381309515:dw||dw:1352381270904:dw|

- hba

no but how y=a(x-1) ?

- hba

I am really sorry but i am in a gap year so i am having problem :(

- hba

@thinker1

look my motive is to find the radius of the cone and its heihgt so as to get the volume.the equation is y=ax+b since a=-b we know that y=ax-a now findthe intersection points of these graph with the two axis by taking the value of yand x 0 seperately get corresponding values of x and y the corresponding value of x gives you the radius and that of y is height if confused now take the help of my drawing and thif you are still in blue tell me iam here for some minutes

thanks

\[V=1/3 \pi r^3h \]
y=ax+b
and a=-b or b=-a
so,
y=ax-a
y=a(x-1)

- anonymous

yes

- hba

Please Tell Me What I Have To Do After This Mathematically because it is hard to understand what you have written :)

- hba

Moreover where did the h come from @thinker1

- anonymous

his the height and y intercept of our line

- hba

@amistre64 Please Take Care Of him :)

|dw:1352384621880:dw|

- hba

I don't get the part i circled :)

- anonymous

THAT IS THE Y INTERCEPT |dw:1352384799109:dw|

- hba

Please write in mathematical form also

- hba

@thinker1

- anonymous

AT X INTERCEPT Y CO ORDINATE IS 0NOW PUT 0 INPLACE OF X IN EQUATION TO GET X INTERCEPT SIMIL. PUT X=0 IN EQUAT. OF LINE TO GET Y INTERCEPT

- hba

@thinker1 I am really thankful to you for helping me out :)

- anonymous

u r welcome
