Answer 2

Hello buddy-

★ Answer-
Total surface area = 2 × area of base + curved surface area

◆ Area of cylinder -
For a cylinder with radius r and height h,
Curved surface area = 2πrh
Area of base = πr^2

Total surface area = Curved surface area + 2 × Area of base
Total surface area = 2πrh + 2πr^2
Total surface area = 2πr(r+h)
