find the surface area of a cylinder with a radius of 4 cm and a height of 2 cm. Use the approximation of 3.14 for pi
The surface area of a cylinder is given by the formula:
Surface Area = 2πr(r + h)
Where r is the radius and h is the height.
Substituting the given values:
Surface Area = 2 * 3.14 * 4(4 + 2)
Surface Area = 2 * 3.14 * 4(6)
Surface Area = 2 * 3.14 * 24
Surface Area = 150.72 cm^2
Therefore, the surface area of the cylinder is approximately 150.72 cm^2.
