information :

1) areas of the sides = (pi) x r x s

2) areas of the base = (pi) x (r^2)

3)volume of the cone = (1/3) x (pi) x (r^2) x h

hi miss dhia! welcome to pf!

(have a pi: π and try using the X

1) areas of the sides = (pi) x r x s

2) areas of the base = (pi) x (r^2)

3)volume of the cone = (1/3) x (pi) x (r^2) x h

what is s ?

actually,

s = side of the conical container (shown in picture).

r = radius of conical container (shown in picture).

h = height of the conical container (shown in picture)

Using your information can you get an expression for the total area in terms of one other variable?

actually, i meant what is s

you need to convert it so that all three areas are written in r and h, and you can easily add them

s = [tex]\sqrt{r^{} + h^{}}[/tex]

i don't know how to put the "surd". sorry ok. :)

in the above equation, i do mean, s = surd(r^2 + h^2).

yup, s = √(r

ok, now write out the formulas for A and for V,

and see if you can find a relationship between them
