Current Year 11 Thread Mark II

Here's the question:

$nr^3 \cdot \dfrac{2}{3}nr^2$

"n" is supposed to be Pi

Thank you, wise mathematician.

Edit: Actually I get why you did 30/2 but not the rest, I think I should focus on other stuff instead. No point in getting caught up on a 1 mark question (or so I hope).

Here's the question:

$nr^3 \cdot \dfrac{2}{3}nr^2$

"n" is supposed to be Pi

What is the actual question though?

Usycool said the dot stands for multiply.

I also need to know the answer of the two expressions added.

Why, thank you. I don't get that latex thing :L

Had a sudden realisation that i'm not good enough to get into medicine...

No problem




Is the question literally just asking you to multiply and add them together?

Here's the question:

$nr^3 \cdot \dfrac{2}{3}nr^2$

Go for it!

Usycool put it into the fancy maths format but I haven't a clue how to do that o.O

πr^2 * 2/3πr^3

π= pie btw

Also if you could work that out...how would you add those two values?

Yes I know this but what are you supposed to be trying to do? There is no actual question stated

Yes, literally that.

I can't believe I'm getting worked up over a maths question :L

Don't worry, you probably are good enough!

Sophie is the way Usycool has put it how u meant it to be?

Btw what do you want me to do? Do you want me to simplify the expression. For which the answer would be:

$\dfrac{2}{3}\pi^{2}r^{5}$

Or do you want me to factorise it for which the answer would be:

$\pi$ $r^{2}$ $(r \times \dfrac{2}{3})$

Sorry for the wait. My Latex skills aren't great!

You can't add them. The expression is in its most simplified form for addtion.

Apparently you can >.<

I'm getting confused.

I could kill my effing neighbours. We don't get on with them and I got woken up at 6am from them hoovering up and banging with a hammer. It's been going on for 7 hours so far, sick of it. Can't revise at all. My mums been round saying she's reporting my neighbour to council again

Thats good if they wake you up, get you revising!



You're predicted all A*-A though aren't you? My friend got accepted this year and he had some B's and C's I think
