The radius of the cylinder is 2cm (diameter/2). The formula for the surface area of a cylinder is 2πr(h+r), where r is the radius and h is the height. Using 3.14 as an approximation for π, we can calculate the outside surface area as follows:
Surface Area = 2(3.14)(2)(8+2)
Surface Area = 2(3.14)(2)(10)
Surface Area = 125.6 cm²
Therefore, the outside surface area of the cylinder is approximately 125.6 cm².
Use 3.14 as an approximation for p.
3. A cylinder with two open ends has a diameter of 4 centimetres and a height of
8 centimetres. Determine the outside surface area of the cylinder.
