The formula for finding the total surface area of a cylinder is given by:
Total Surface Area = 2πr(r+h), where r is the radius of the base and h is the height of the cylinder.
Given that the radius of the cylinder is 5cm and the height is 20cm, we can substitute these values into the formula:
Total Surface Area = 2 * 3.14 * 5(5 + 20)
Total Surface Area = 2 * 3.14 * 5(25)
Total Surface Area = 2 * 3.14 * 125
Total Surface Area = 6.28 * 125
Total Surface Area = 785 cm²
Therefore, the total surface area of the cylinder is 785 cm².
