Thanks Chris,

I tried to give you points but the site won't let me.     

It is playing up pretty badly for me today :((

Thanks Alan and lakofbryn :)

It is easy to show this but as a mental exercise I really like what Alan did.

It took me a little while to understand it though.    

Hi Alan, it is really good to see you - we have missed you here  :)

Behave yourself Guest Troll,

BruceWayne just ignore him.

If you do not want to be a target for bullies in your life the first thing you must learn is how to totally ignore bullies, and not let them get under your skin.

A forum is a really good place to learn that because you always know that they cannot punch you in the nose.

If you ignore them it makes them mad because there is absolutely nothing they can do about it.

You can sit back and be silently very smug about it though :)

Thanks guest :)

That is a fair comment :)

There are 8 numbers so the prob of getting any other than 20 is

7/8

=7/8*100%

Why do you need help?

A cone is a circluar pyramid.

The volume of any pyramid is 1/3   the volume of the corresponding prism.

The volume of any prism is the are of ther base  times  by the height.

The area of thr circlular base is  pi*r^2

So now you should be able to work it out.

Post your working (not just answer)  and I will check if you want :)

abs(-6)    I will put this into the calc and see what happens :)

abs(-6)=  6

There you go, that is how :)

I don't  think that that is alowed rarinstraw LOL
