total surface area of cylinder = 2πr(r+h)
=2×3.14×21(21+20)
=2×3.14×21(41)
=5407.08cc
=2×3.14×21(21+20)
=2×3.14×21(41)
=5407.08cc

Hey....
Your answer is here.
r=21 cm,h=20 cm
surface area of cylinder = 2πr(r+h) = 2×(22/7)×21(21+20) = 2×(22/7)×21×41 = 2×(22/7)861 = 861×44/7 = 37884/7 = 5412cm^2
Thankyou Buddy...
