2. irishmolly

that is supposed to be a cylinder btw!

3. julianassange

Ok, so make a surface map to help you: ill draw it

4. julianassange

5. julianassange

That is the shape if you take it out, for example

6. irishmolly

Ok

7. julianassange

Wait, do u happen to have a textbook for this?

8. julianassange

Because the equation for it is the way to do it.

9. irishmolly

No, i wish i did

10. julianassange

Gimme a minute

11. irishmolly

do you know what the equation is to do it

12. irishmolly

ok

13. julianassange

Surface Area of a Cylinder = 2 pi r 2 + 2 pi r h

14. irishmolly

Okay, so let me try to do that on a calculator

15. julianassange

So, if you know the order of operations, this is fairly easy.

16. irishmolly

so 2 pi times 4 squared plus 2 pi times 4 times 15 ?

17. irishmolly

i got 427

18. julianassange

Wait... you said calculator, right?

19. julianassange

Because when you do this this is supposed to be done by not calculator, but paper and pencil.

20. julianassange

So, use the order of operations and you'll get the answer.

21. irishmolly

ok, thanks!

22. julianassange
