Thank you for the thanks, though today has been an off day for me I have to say..

Nice one! You are a lot better at drawing diagrams than I am apparently.

πr(g+r), where r is the radius of the base and g is the slant height. 

Hope this helps!

He can't access google docs? But yeah you should be able to use Word, just going through the same process.

I can't get enough from the description. Copy the picture into google docs, then go into file. Download as PDF, then click the up arrow on the pop up on the bottom left part of your screen. Give it a unique name, making sure you keep the .pdf, and download it to your desktop. Then go to upload the image, and click choose file. Type in the name you gave it, and then you can upload it.

Don't let the fact that the triangle is upside down throw you off. Say X is where you drop a perpendicular from Q to PR. If we set PR as the base, and XQ as the height, after that it's straightforward. \(B \cdot H \cdot 1/2 = 4 \cdot 3 \cdot 1/2 = 6\) .

Hope this helps!

It's just a website commonly used for screenshots. It's safe, don't worry. Anyway, I'm afraid I'm not very good at these types of problems, so I can't help you.

Sorry! Someone like CPhill or someone who is much better than I am will come along and help.

\(8 \cdot 27 \cdot 125 = 27000\), and they are all relatively prime. So the sum is \(8 + 27 + 125 = 160\). I got this by looking up 3 factors of 27000, and it gave me \(2^3 \cdot 3^3 \cdot 5^3 = 27000\).

Hope this helps!

Which angle are you talking about?

-1 as a fraction is the same thing as -5/5. .2 goes into -.4 -2 times, while it goes into 1 five times. So you have -5/5 + -2/5 = -7/5

Hope this helps!
