Cut a cylinder into two halves. The front of the cylinder is a square. The volume of each half cylinder is known to be 25.12 cubic centimeters. How many square centimeters is the surface area of each half cylinder? Please don't use some special symbols. I can't understand them
If the section is a square, the ground diameter = height, and the volume of each half cylinder is 25.12 cubic centimeter, the cylinder volume is 50.24 cubic centimeter. The cylinder volume = bottom area * height = π * r & # 178; * 2R = 6.28 * r & # 179; = 50.24r = 2 half cylinder bottom area = 2 half circles = 1 circle = π R & # 178; = 3.14 * 2 & # 178; = 12.56 arc side area
