# A cylinder with radius r and height h is closed on the top and bottom. Which of the following expressions represents the total surface area of this cylinder?A. 2πr(r+h)B. πr(r+2h)C. πr(2r+h)D. 2πr2+h

Given,

Height of cylinder = h

Total surface area = area of curved surface + area of circular bases

= 2πrh + 2πr2

= 2πr(h+r)
