Find the surface area of a cylinder with a radius of 4 cm and a height of 2 cm. Use the approximate of 3.14 for pi.
The formula for the surface area of a cylinder is given by:
SA = 2πrh + 2πr^2
where r is the radius and h is the height of the cylinder.
Given that the radius is 4 cm and the height is 2 cm, we can substitute these values into the formula:
SA = 2 * 3.14 * 4 * 2 + 2 * 3.14 * 4^2
SA = 25.12 + 100.48
SA ≈ 125.6 cm^2
Therefore, the surface area of the cylinder is approximately 125.6 square centimeters.
