WebSurface Area of Cylinders (1) Right Circular Cylinder Curved surface area = the perimeter x the height of the cylinder, i.e. S = 2 π r h The area of each of the flat surfaces, i.e. of the ends, = π r 2 The total surface area = 2 π r h + 2 π r 2 = 2 π r ( r + h) Example: WebVolume of a cylinder formula is given by V = πr 2 h cubic units Substituting, So, 200 = 3.14× r 2 × 20 r 2 = (200)/ (3.14 × 20) =200/62.8 = 4 Therefore, r = 1.78 cm Therefore, the radius of a cylinder = 1.78 cm. Things to Remember A cylinder is a three-dimensional shape with its bases circular, parallel, and congruent with one another. shark no hair wrap vacuum cleaner
