The formula for the surface area of cylinder is given by:
Surface Area = 2πr^2 + 2πrh
Given that the radius (r) is 4 cm and the height (h) is 2 cm, we can substitute these values into the formula and calculate the surface area.
Surface Area = 2π(4^2) + 2π(4)(2)
Surface Area = 2π(16) + 2π(8)
Surface Area = 32π + 16π
Since the approximation of π is given as 3.14, we can substitute this value into the equation.
Surface Area = 32(3.14) + 16(3.14)
Surface Area = 100.48 + 50.24
Surface Area ≈ 150.72 cm^2
Surface Area = 2πr^2 + 2πrh
Given that the radius (r) is 4 cm and the height (h) is 2 cm, we can substitute these values into the formula and calculate the surface area.

Surface Area = 32π + 16π
