Surface of a cylinder?

New rolls are available in rolls.they cylindrical roller has a diameter of 102 cm and a length of 137 to the field of packaging putter Please show all work thanks!

package depends on the external covering the top and bottom or not. The surface of the cylinder is the circumference times the length: A = LC circumference is π times the diameter: D = C = πD 102cm, 137cm L = C = = A = 102π cm = 320.44cm 320.44cm * 137cm 43 900 cm ² If you need to add top and bottom, these are the areas of circles, the area of a circle is π times the radius squared: A = π r ² radius is half the diameter: r = D / 2 = 137cm / 68.5cm 2 = A ² = R ² = 68.5 cm ² = π π π ² = 4692.25 cm ² 14741.14cm There two of them, if the count, so 2 * 14741.14cm 29482.28cm ² ² = Add to the external surface 29482.28cm ² + 43 ² = 900 cm 73382.28 cm ² total
