Best Answer

To find the area of a cylinder you need: (π=pi) Therefore the surface area is all of those added together. or simplified Your answer: A=179.4878 Keep in mind that this is the surface area of the top bottom and side, or the total surface area of the geometric object. Be certain the question isn't just being asked of the cylinder wall itself, if that were the case the formula would simply be 2πrh and the answer would then be about 100.5
