The surface area of a cylinder is 156.52 square meters, and the side area is 100 square meters. What is the radius of the bottom of each cylinder? real

Surface area of cylinder = side area + 2 times bottom area
SO 2 times the bottom area = 156.52-100 = 56.52 (M2)
Base area = π R ^ 2 = 56.52 / 2 = 28.26 π is about 3.14
So r = 3
