Find the circumference of the circle. That will be your rectangle length ( or width, english isn't my first language). Then find the area of the rectangle. Find the area of the 2 circle. Add everything up and you're done :)

2. Emily778

how do i find the circumference?

3. MarcLeclair

Circumference of a circle = 2(pi)(radius) Radius= diameter /2

4. Emily778

i got 43.96

5. MarcLeclair

Really what you're trying to find is the area of each shape. The only way to find the surface area is to find each shape separatly |dw:1369361531337:dw|

6. Emily778

what do i do next?

7. MarcLeclair

then as yoou can see in the picture thats the length of the rectangle. so you multiply it to the height for the area of the rectangle.

2107pi+49pi (includes the base)

9. MarcLeclair

.. I think someone should understand what they are doing not feed them the answer.

10. priyeshpatel375773

sorry

11. MarcLeclair

Its okay :D its just sometimes people get the wrong feeling of math when it can be so fun :(

12. Emily778

none of you are helping..

13. MarcLeclair

I just told you what to do. Look at the drawing. Find the area of the circle and the area of the rectangle. Don't you have formulas for both?

14. Emily778

no.

15. priyeshpatel375773

hope this helps

16. MarcLeclair

Can't draw on a laptop :P

17. Emily778

can you just tell me the equation?

18. priyeshpatel375773

Did this helped

19. Emily778

No. I did not get any of the answers listed.

20. priyeshpatel375773

subtract 49pi from my answer that should give you answer with no base of a cone I dont know if container is open or not

21. Emily778
