    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 :)

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

    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|

    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.

    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?

    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
