: How does one find the Surface Area of this composite solid with rounding the results to two decimal places:
There is half a sphere with a radius of 5.1 attached to a cone with the height of 12.2. Note:The radius of the of the sphere is shared with the cone. This question is from textbook

Find the SA of a Cone here --> http://math.about.com/od/formulas/ss/surfaceareavol_2.htm.
Find the SA of a Sphere here --> http://www.teacherschoice.com.au/Maths_Library/Area%20and%20SA/area_2.htm
Understand that the figure you describe is actually 1/2 of a sphere attached to a cone. Also note that the cone's base is not included on the SA in this case (it is replaced by the 1/2 sphere)
Is that enough info to get you going?
