Answer:

2198 cm²

Step-by-step explanation:

Total surface area of a cylinder = 2πrh + 2πr²

Radius, r = diameter/2

= 20cm/2

= 10 cm

Height, h = 25 cm

Total surface area of a cylinder = 2πrh + 2πr²

= 2*3.14*10*25 + 2*3.14*10²

= 1,570 + 6.28*100

= 1,570 + 628

= 2198 cm²

Total surface area of a cylinder = 2,198 cm²
