To find the surface area of a cylinder, you need to consider the formula which includes the areas of the two bases and the lateral surface area. The formula for the surface area of a cylinder is:
Surface Area = 2πr(r + h)
Given that the base radius (r) is 4 units and the height (h) is 5 units, you can substitute these values into the formula to find the surface area:
Surface Area = 2π(4)(4 + 5)
Surface Area = 2π(4)(9)
Surface Area = 2π(36)
Surface Area = 72π
Therefore, the surface area of the cylinder with a base radius of 4 units and height of 5 units is 72π square units.
