Find the volume , curved surface area and the total surface area of a cylinder with diameter of base 7 cm and height 40 cm.
Choose the most appropriate option: A) 952cm^2 B) 957cm^2 C) 954cm^2 D) 958cm^2 E) None of them
Volume = ∏r2 h = ((22/7)x(7/2)x(7/2)x40) = 1540 cm^3. .   Curved surface area = 2∏rh = (2x(22/7)x(7/2)x40)= 880 cm^2 .   Total surface area = 2∏rh + 2∏r2 = 2∏r (h + r)   = (2 x (22/7) x (7/2) x (40+3.5)) cm2   = 957 cm^2   Answer is 957cm^2
