What is the height of a cylinder if the height is 226.08 square meters and the radius is 3 meters

27 meters
18 meters
3 meters
9 meters

The height is in the answer if the neither is 226.08 is the height

Start by forming an equation relating radius, height, and surface area, and fill in the known quantities. 

Break the object up into two-dimensional surfaces: two circles (top and bottom) and a rectangle (wrap around) 

Area of a circle = pi * r^2 

Area of a rectangle = base * height 
this is tricky though because the base is supplied by the circular circumference (2 * pi * r) 

If you combine these properly, the result should be equal to surface area, and be determined by radius and height. After that, it is just a matter of plugging in known variables and solving.
